How do you watch CPAN modules of interest?

This post is really a request for advice. I’m sure there must be a solution out there, I just haven’t found it yet.

Imagine you have a module that pulls in a bunch of prerequisites. You want to watch those prerequisites (and maybe all the way down the the dependency tree) for test failures. Maybe you also want to be notified of new releases. You might even want to try extracting the most recent section of the changelog.

What’s the best way to get these sorts of notifications? If you can’t get it all from one place, is there a tool to aggregate the data sources? If not, that sounds like an interesting project…
