I recently ran this on my system: 
perl -MCPAN -e 'CPAN::Shell->r'

[download]
If the CPAN module is installed, that will give you recommendations about which modules to upgrade on your system. I think that's a great trick!

In my case, I found that most of the result list was comprised of modules that we'd installed, tried out, and then abandoned, and that's way they are out of date now.

So now I'd like the answer to a more difficult question: "Show me which modules haven't been used in last X Months". A function like that would be useful to find which modules we could just nuke, or not re-install if we need to re-create everything.

The solution that comes to mind is some sort of "module logging" which would keep track of the last time a module was "used". I know of no such facility in Perl, though. How do other folks handle the process of weeding out abandoned modules? Any good automated solutions out there?
