wfsp has asked for the wisdom of the Perl Monks concerning the following question:

I'm trying to install File::BOM into a local lib on a shared webhosters server. From Windows I can SSH in and start the cpan shell. Installing simple modules (pure perl, no dependancies) is working fine so I assume I have cpan's MyConfig.pm set up properly. I've included it the end of the post.

Suspecting a version issue with File::Path I had previously installed it in the local lib (after restarting cpan a few times). But the tests are not finding the latest version.

Shouldn't the cpan shell find the File::Path in lib? If it could it may fix some of the other errors.

Also 

Can't locate Archive/Tar.pm in @INC  (@INC contains: t/lib /xxxxxx/.cp

The xxxxxx _isn't_ my home dir (a truncated version of it, the leading dir is missing) which is why it can't find it (or, presumably, the local File::Path).

Is there anything I need to do to get cpan shell to use a correct @INC? Here's my MyConfig.pm

Re: Installing Module::Build into a local lib using the cpan shell
by ikegami (Patriarch) on Jul 29, 2009 at 14:30 UTC
    You normally tell Perl where to find locally installed modules by setting env var PERL5LIB. It's no exception here. However, this will fail if the (.t) test file uses taint mode (-T).

      Thanks, that got me a lot further along the road. :-)

      To impose a bit more, I'd appreciate it if you could run your eye over the make test output I'm getting now.

      Again, thanks.
