Ahh. That's an idea worth considering. So for dependencies on
libraries, we would prefer ">=" wildcards to "-*" wildcards?

I'm also concerned about what happens when the library evolves to the
point where it finally breaks backwards compatability. The only thing
we can do for that, I think, is to compile a database of binary
packages which are affected. It's not enough to just remove them from
the server, because users could have them already on their hard
drives, or pressed onto a CD.
