Here is how i achieve this at work. On a system which has internet access use minicpan to create mirror, transfer the files to your system that doesn't have internet access. Configure cpan/cpanm to point to this mirror. Install modules as usual. Of course you can just put this behind a web server to make it easier for multiple clients to use the same mirror.

Update: added last sentence.
