I recall that Cabal had (at some early design stage) the ability to specify a range of version numbers on each package dependency, e.g. Foo requires Bar, any version between 1.2 and 1.8. The ranges are open, so you could say "anything > 6.2" for instance.

Cabal does have this: you can specify version ranges, and even union/intersect them. I agree with everything else in Malcolm's message... Cheers, Simon
