I don't think CPAN itself has these stats, but you asked in the right place. If someone has already collected such info, you probably can find her/him here.

If CPANTS were up, you could look for Moose and look at the distributions that depend on it. But it is not working (at least for me).

With regard to very popular modules, the Phalanx Project has a (possibly outdated) list of the 100 most popular ones.

And then there is Google Search Code, but it doesn't summarize its findings (yet). Or maybe I don't know the last news. Try http://www.google.com/codesearch?q=Moose+lang%3Aperl&hl=en&btnG=Search+Code.

Update: got the link to the Phalanx project right, thanks to j3's Re^2: Which CPAN modules are most used/depended upon?.
