[xmonad] Recommended setup for coding

I would like to try some haskell coding with xmonad. What is the best xmonad install for this purpose? Is it essential to use the cabal version? What is your opinion about the "Haskell Platform" instead of ghc --> http://sporkcode.wordpress.com/2009/07/11/installing-the-haskell-platform-in... So far i am using ghc/xmonad-0.9.1 from debian sid, installed on ubuntu 9.10. If possible i would like to keep this unchanged, because everything works fine. Ralph
