You should find that on most systems that:

   perldoc perllocal

/J\

How about this one:

perl -MFile::Find -le '
    for my $inc (@INC) {
        find(sub {
                   return unless /pm$/;
                   $_ = $File::Find::name;
                   s{^\Q$inc/}{};
                   s{/}{::}g;
                   s{.pm$}{};
                   print
                 },
                 $inc);
    }'

We'll see how long it takes to get golfed. :-)

Update: This looks potentially very useful too: Search @INC And Display Modules.

HTH,

use HTML::Perlinfo;

perlinfo(INFO_MODULES);

I've always been fond of
  perldoc -t perllocal | grep Module | cut -d\" -f 3 | sort | uniq
with maybe a | vgrep tacked on for fun.
