from a root console, run the command "cpan" and "r" in its prompt... wait some time and it will list all visible installed perl modules

To see Debian installed Perl modules, this should help:
aptitude search ~ilib | grep perl
If you've installed modules on your own, try this script:
#!/usr/bin/env perl
use strict;
use warnings;
use ExtUtils::Installed;

my $installed = ExtUtils::Installed->new();

foreach my $module ( $installed->modules() ) {
  my $version = $installed->version($module) || "???";
  print "$module -- $version\n";
You can also use these commands from Perl itself:
perldoc perlmodlib
perldoc perllocal
Those show standard modules and modules you installed (by hand or via CPAN or CPAN+ but not via APT tools, I think.)

thx a lot !

that's other way:

show perl packages installed via aptitude, synaptic, apt, etc.
# dpkg -l "*perl*" | grep "^ii"
show all *.pm files:
# perl -e 'print join "\n", @INC' | egrep -v "^\.$" | xargs -i{} find {} -name "*.pm"
