Probably more intesting than the node I linked to above is the follow-ups (eg. this one for debian systems). There's good info on how to install specfic versions of CPAN modules.

If you're more worried about your custom (non-CPAN) modues, then CVS or similar may be an option. Good use of tags and branches makes it easy to keep code consistent across multiple systems.

But it really depends on:

  1. What platform you're running on.
  2. What you're deploying to (eg. servers, desktops, random users on the web)
  3. And maybe how you want to handle CPAN packages.
