That's correct.  We can handle documented requirements which aren't 
managed dependencies, but if you want real dependency management, the 
dependencies (for now at least) have to be Gems.

Do you mean like:
gem --remote-install somegem

..and it downloads and installs the gem and all of its dependencies?  If 
so, you can already do this (of course, it needs to have the kinks worked 
out, but the basic functionality has been there since RubyConf).
