which did not look alright. Clearly cpanm is not correctly installed at least in terms of where it is placing modules. Looks right to me. You should find `/home/hsmyers/perl5/perlbrew/bin/cpanm` to be a link to the current selected perl. `[~/usr/perlbrew/bin]$ dir lrwxrwxrwx ... a2p -> ~/usr/perlbrew/perls/current/bin/a2p* lrwxrwxrwx ... c2ph -> ~/usr/perlbrew/perls/current/bin/c2ph* lrwxrwxrwx ... corelist -> ~/usr/perlbrew/perls/current/bin/corelist* lrwxrwxrwx ... cpan -> ~/usr/perlbrew/perls/current/bin/cpan* ...` [download] `[~/usr/perlbrew/perls]$ dir lrwxrwxrwx ... current -> perl-5.12.3/ ...` [download]	[reply] [d/l] [select]

Shouldn't it point to the original cpanm? Since after the reboot I'm no longer running 5.8.1? Color me confused... I will check what you've posted to see what it shows though. Update: Here is what I get: `hsmyers@ubuntu:~$ cd /usr/perlbrew/perls bash: cd: /usr/perlbrew/perls: No such file or directory hsmyers@ubuntu:~$ cd ~/usr/perlbrew/perls bash: cd: /home/hsmyers/usr/perlbrew/perls: No such file or directory hsmyers@ubuntu:~$ cd /usr hsmyers@ubuntu:/usr$ cd perlbrew bash: cd: perlbrew: No such file or directory` [download] --hsm "Never try to teach a pig to sing...it wastes your time and it annoys the pig."

Shouldn't it point to the original cpanm? It should point to the `cpanm` installed by the Perl installation you indicated you wanted to use via `perlbrew switch`. Are you saying it doesn't? Here is what I get: That's not the file `which` said you were using.	[reply] [d/l] [select]

I'd love to help you with perlbrew, but I find it too complicated, for simple debug, try `perl -V` or `perl -e " die $^X "` This works for me download, make, install, perl 5.8.1 `wget -c http://cpan.org/src/perl-5.8.1.tar.gz tar -zxvf perl-5.8.1.tar.gz cd perl-5.8.1 ./Configure -des -Dprefix=~/p/5.8.1/ make install` [download] use this perl by making it first in path `export PATH=~/p/5.8.1/perl/bin:$PATH` [download] verify path `which perl perl -V perl -e "die $^X"` [download] verify path from cpanp `$ cpanp CPANPLUS::Shell::Default -- CPAN exploration and module installation ( +v0.9105) CPAN Terminal> !warn $^X` [download]	[reply] [d/l] [select]

You didn't ask a question. Are you asking how to use the `cpanm` installed by `/usr/bin/perl`? If so, `perlbrew switch /usr/bin/perl hash -r cpanm` [download]	[reply] [d/l] [select]

You are right, I tend to treat questions like some treat documentation (but it's self-evident... :) ), I shouldn't but I do. This is the third way that I've see to install `cpanm`, but you I trust! I'll give it a shot and see what happens. Still wish I didn't have the knack of turning speed-bumps into climbing walls... Update: Clearly I don't understand what you've said. I tried the following: hsmyers@ubuntu:/usr$ perlbrew switch /usr/bin/perl /usr/bin/perl is not installed hsmyers@ubuntu:/usr$ which cpanm /home/hsmyers/perl5/perlbrew/bin/cpanm hsmyers@ubuntu:/usr$ sudo cpanm Chess::PGN::Moves [sudo] password for hsmyers: Chess::PGN::Moves is up to date. (0.05) hsmyers@ubuntu:/usr$ hash -r hsmyers@ubuntu:/usr$ cpanm Can't write to cpanm home '/home/hsmyers/.cpanm': You should fix it wi +th chown/chmod first. hsmyers@ubuntu:/usr$ sudo cpanm Usage: cpanm [options] Module [...] Try `cpanm --help` or `man cpanm` for more options. hsmyers@ubuntu:/usr$ hash -r hsmyers@ubuntu:/usr$ sudo cpanm Usage: cpanm [options] Module [...] Try `cpanm --help` or `man cpanm` for more options. [download] With the results as shown. Maybe I wasn't clear (the not asking questions thing) what I need is a `cpanm` that works with `perlbrew`. What I have now is one that only installs in the original environment. As a for instance, the attempt to install `Chess::PGN::Moves` shows a reference to the one installed under 5.10, not to one installed under 5.8.1. Further, the first line is as you had shown and got the result that you see. If I now do a quick test: `hsmyers@ubuntu:/usr$ perldoc Chess::PGN::Moves No documentation found for "Chess::PGN::Moves".` [download] This shows that no attempt to use `cpanm` has yet worked in the 5.8.1 context. Since I have no idea of what any of the commands you showed mean, I have no idea of what might be wrong---clearly something is. Given the lack of any directory off of `/usr/` named `perlbrew`, I wonder about my installation of `perlbrew`---did I mess it up somehow? The only thing that I have that matches what you've said is that I do have a `/usr/bin/perl`. Being curious I did: `hsmyers@ubuntu:/$ perlbrew list perl-5.8.1 * /usr/bin/perl (5.10.1)` [download] The documentation didn't say what the '' stands for, but if I do: hsmyers@ubuntu:/$ perlbrew install /usr/bin/perl Unknown installation target "/usr/bin/perl", abort. Please see `perlbrew help` for the insturction of install command. [download] This might explain why my attempt to `perlbrew switch /usr/bin/perl` didn't work. The more I look at your first post, the more I'm wondering why I don't have a `/usr/perlbrew/` directory. After all if I screwed up `cpanm` to to point of non-usability, doing the same to `perlbrew` should be dead bang easy... IMPORTANT Update:* Found the problem or at least found something that works (can't speak to its correctness beyond that) Did this: Removed `cpanm` as installed by `perlbrew` Removed `cpanm` as installed by `cpan` Reinstalled `cpanm` using `perlbrew install-cpanm` Issued magic incantation `sudo chown -R hsmyers /home/hsmyers/.cpanm` Tested by `cpanm`-ing first dependency and rerunning `perl Makefile.PL`---still have dependencies reported, but one less than before! Continued with installs and final testing with a clean result from the makefile Like I said, since I don't even have a Linux merit badge, let alone a wizard's staff, this is slightly suspect. I think that removing the original `cpanm` was probably unnecessary but did so as a clean slate kind of thing. I am convinced that the problem came down to the simple lack of correct ownership for the `.cpanm` directory, probably nothing more than that. This matches well with the countless reports on the net about how easy all of this was supposed to be---it's always easy if you know what the hell you are doing!. As per usual, a ton of thanks to all who helped and made offers of help—you and all of the other Monks make this place the incredible resource that it is! --hsm "Never try to teach a pig to sing...it wastes your time and it annoys the pig."
