Won't ask you how :) Here's a MFTL sol'n :)

You need to devise a package description/configuration language
that is declarative rather than procedural.

What comes to my mind would be some sort of "logical language", maybe
something based on Prolog. That the statements as your example would
be implemented with it and then the package interpreter would
handle the "procedural" aspects of upgrading.

No religious wars, all right? :)
