The rPath Linux package management tool, conary, has a nice
solution to the problem that software version numbers have
inconsistent lexical ordering conventions between projects and sometimes
within the same project. It does not compare version numbers at all,
and (as far as I can tell) asks the package repository for the most
recent package, unless you specify a particular version. Perhaps Cabal
could do something similar?
Of course, this way you can't express "I want version >= 1.2" which is
kind of a bummer.
