I have to revise my last recommendation. The signature of the second

Thanks for all the responses, both on the list and off.

I like this idea too, because if you end up wanting to port this package
manager to CLR, Parrot, or JS, you're less tied down to the package formats
of specific platforms.
Heck, even if Clojure was ported to Ruby (not that there'd be any point to
do that), you could wrap the Gems framework.
