in thread Listing all of the perl modules installed

Have you tried it on debian?

It relies on .packlist files, and IIRC, debian (or some other distro) removes these files, thus instmodsh doesn't work

These tool could do it
which_pm / Module::Which
pm_which / Module::Util
pmlist / App::PMUtils
App::Module::Lister

These also help

App::pmuninstall/pm-uninstall

cpan-outdated/ App::cpanoutdated

cpanm/ App::cpanminus
