I take it that since you've got this far you've installed the developer tools, which I think was tricycle's problem.

I've been having related problems doing pretty much the same thing. In the end I installed the DBI and DBD::mysql packages manually. They seem to work fine. The problem I've been seeing with this and other CPAN-based installs is that newer modules apparently depend on perl 5.6.1 rather than the 5.6.0 that ships with OSX. I've compiled perl 5.6.1 and 5.7.2 but they fail a few of the tests run by make test (including one of the POSIX tests) so I'm a bit leery of actually installing them.

On a side note, the fink project is apparently working on providing the DBI and DBD modules; the relevant modules are in the current-unstable tree. Wait a while and the problem might go away :-)

Update: For completeness, I'll just add this pointer to a previous, more comprehensive thread on MacOSX and perl.

Update^2 (belated): Having installed perl 5.6.1 using the instructions codified here (which basically say: ignore my above concerns :P), I've found that the perl -MCPAN -e shell route works (almost) flawlessly. The only significant problem so far has been the DB_File module, which is one of the modules which originally failed make test anyway.

HTH, Tim

Hi Tim, Thanks for the advice. I've installed the developer tools, but as you found, this did not make all my troubles go away.

As you suggested, I attempted a manual install of DBI. However, this also generated errors. Running the makefile produces the following error:

Any advice on resolving this problem? I've got the idea that perl is not configured to look in all the right places for included modules, but am not sure how to fix this.

Many thanks,

Kevin

Hi Kevin,

A good resource is the macosx email list at perl.org.

You can take subscribe or just browse the archive at:

Hi again,

I think that perl is looking in the right places; it's just that MD5 is yet another external module you will have to install. If I recall correctly the Digest::MD5 module installed from the perl -MCPAN interface without any problems.

Unfortunately, as you've discovered, the catch with manual installation is that module dependencies don't get followed automatically. Of course, for a control freak like me, that's a plus :-)

Tim

Here's what I did.  I followed the advice of Elaine -HFB- Ashton and l
+ooked at my CPAN Config.pm file in it I found that _MY_ Config.pm fil
+e had "blanks" next to important settings like tar, unzip and make.  
+Filling in those blanks fixed CPAN.

Here are the steps I took:

cd /System/Library/Perl/CPAN
sudo perl -MCPAN -e shell

At the CPAN shell I typed
o conf

o conf allowed me to look a my configuration.  If you see things like:

make

then you need to adjust those settings.  CPAN can't find make.  That's
+ bad.  To figure out where these programs are you can type:

which make

Which should return:

/usr/bin/make

Mostly the programs listed in o conf should be in /usr/bin but I would
+ check.

To edit Config.pm you'll need to do something like this:

sudo emacs Config.pm  (choose the editor of _your_ choice)

You'll now see entries like:

'make' => q[ ],

You'll want them to look like this:

'make' => q [/usr/bin/make],

Not every entry in my Config.pm has a setting.  For instance I don't h
+ave lynx, and so there's no entry.  Keep two terminals open while you
+ do this.  So if here is an entry and you're not sure about it you ca
+n do a which #### on the entry to see where/if you have it.

Good luck

Oh and if  you choose emacs CTRL-S will save and CTRL-C will get you o
+ut of emacs.
