I wanted to experiment with the CPAN module so I run perl -MCPAN -e shell, configured it and tried to reinstall two modules that I previously had installed by hand. Everything went ok and the modules ended up under the PREFIX directory I specified during CPAN configuration. This line caught my attention: Appending installation info to /home/hue/lang/perl/modules/lib/perl/5.8.7/perllocal.pod. I went to see that file with perldoc and discovered what seems to be an installation log. Great! It reads:

       Sat Sep 24 12:24:26 2005: "Module" Digest::SHA
       -   "installed into: /home/hue/lang/perl/modules/share/perl/5.8
+.7"
       -   <blah>
       Sat Sep 24 12:30:21 2005: "Module" Language::Befunge
       -   "installed into: /home/hue/lang/perl/modules/share/perl/5.8
+.7"
       -   <blah>

But when I go to the filesystem to check this, I find:

|-- lib
|   `-- perl
|       `-- 5.8.7
|           |-- Digest
|           |   `-- SHA.pm
|           |-- auto
|           |   |-- Digest
|           |   |   `-- SHA
|           |   |       |-- SHA.bs
|           |   |       `-- SHA.so
|           |   `-- Language
|           |       `-- Befunge
|           `-- perllocal.pod
|-- share
|   `-- perl
|       `-- 5.8.7
|           `-- Language
|               |-- Befunge
|               |   `-- <blah>
|               `-- Befunge.pm

That is, SHA.pm is under lib/perl/5.8.7 but Befunge.pm under share/perl/5.8.7.

I did export PERL5LIB=~/lang/perl/modules/lib/perl/5.8.7 and now I can use Digest::SHA; but when I use Language::Befunge; I get the usual error message telling me that Language/Befunge.pm is not in @INC. If I export PERL5LIB=~/lang/perl/modules/share/perl/5.8.7, I can use Language::Befunge; but not Digest::SHA. As expected :^).

My question is, why perllocal.pod says both modules are in share/perl/5.8.7 when it's not true?
