As long as you have make and a compiler for modules with XS, the CPAN
shell works very well -- IIRC modern Perls install a 'cpan' script at
/usr/bin that will startup the shell for you, otherwise you need to

Installed packages I'm not so sure about, but searching for specific
packages from the CPAN shell is pretty easy:
cpan> m /LWP/
Module Babble::Transport::LWP (A/AL/ALGERNON/Babble-0.07.tar.gz)
Module Gtk::LWP (L/LU/LUPUS/Gtk-Perl-0.7008.tar.gz)
Module Gtk::LWP::http (L/LU/LUPUS/Gtk-Perl-0.7008.tar.gz)
cpan> d /LWP/
cpan> ls CWEST
2233 2002-09-22 CWEST/ACME-Error-0.03.tar.gz
entering a '?' at the shell prompt gives you some more options.

Many times these are packaged in a single Bundle:: module. For
instance, with LWP you can do:
cpan> install Bundle::LWP
and it will install all the referenced modules.
