I can see it turning into something like CPAN, where you can easily get a module and its required dependencies, without really having to worry about version compatibility, etc, etc. ANy ideas on why it's not more widely used?

Looking at the docs for 0.65 (README.overview), I see it says that it's 
based on bud.  Is that correct?  Are bud and rebuild the same thing, or 
did the project switch over to using bud instead of rebuild?
