I was using rpms until they broke multi-monitor support, then I switched to using cabal, which worked when I first installed it, but now it broke on it's own. And when trying to fix it several packages where broken again. For no reason. Cabal also doesn't do dependency management. So you have to try to install something, it'll complain it doesn't have X, then you have to install X, then it complains it doesn't have Y and so on.
