This is really handy. ++

I think I have an idea that could improve it. Also outputting a "least-fuss-at-top" or "leaves first" list of the modules would help to keep better control of a long installation process. You could first install the modules with no dependencies, then the ones that relied on them, then the ones that relied on them, etc very easily.

This is true for the cpan shell which sometimes often doesn't recognize a failed install and keeps going with the result of mass test failings and further failed installs. Let alone wacky installation environments like webhosting and no shell-access. It would be really nice to have a checklist to go bottom up.
