I just recently applied a patch here to support ghc-6.8, sent in by a
contributor. There's two issues, one is building Cabal with ghc-6.8, and
the other is using a recent Cabal version to work with ghc-6.8 at
runtime. The generated paths module has to compile with the target
compiler, including older ghc and hugs, nhc etc.
