Check out Module::ScanDeps and the “scandeps.pl” utility that comes with it. It can do a static (and recursive) analysis of your code for dependencies as well as the %INC dump either after compiling or running the program. Please note that the static source scanning always errs on the side of including too many dependencies. (It … Read more

CPAN.pm (cpan) is the original client. It comes with Perl, so you already have it. It has the most features. It has a lot of configuration options to customize the way it works, though virtually everyone accepts the default installation. It integrates easily with local::lib. cpanminus (cpanm) is an attempt to make a zero-configuration client … Read more
You can still use ppm, but it is not recommended. Run CPAN client from the Strawberry Perl or Strawberry Perl (64-bit), sub folder Tools, entry in the Start menu. Type install Module::Name there.
