In general, you shouldn't have to worry about dependencies. Use a tool like [cpan][1], [cpanp][2], or [cpanm][3] (all of which process dependencies, download modules, and compile, test, and install them) to install modules. I currently use cpanm to install modules into my current directory. It is easy to install: wget -O- http://cpanmin.us | perl - App::cpanminus and use: cpanm Some::Module If you want to find the dependencies programmatically for some reason, take a look at how cpanm does it, or use [CPAN::FindDependencies][4]: #!/usr/bin/perl use strict; use warnings; use CPAN::FindDependencies; for my $dep (CPAN::FindDependencies::finddeps("Moose")) { print $dep->name, "\n"; } N.B. All of the above methods use the latest versions of the modules (not necessarily what will be in a given version of CentOS) and depend on the modules accurately stating their dependencies, which is not always the case (for instance, Clipboard requires IO::All, but, the last time I installed Clipboard, IO::All was not in the dependency list causing a test error). All of them also require you to have network access to a CPAN mirror (possibly a local mirror you have set up).
