Yeah, cabal isn't quite there yet. People are aware of the issues and are working on them, but it's a slow road. As a workaround, my modus operandi right now is to use virthualenv and build everything in there. I understand cabal-dev provides similar functionality, but I haven't used it. I've never had dependency conflicts when I build something from hackage in a virthualenv, so if you're still interested in trying it you might want to give that a shot.
