I installed it on Windows 7 and then re-installed a lot of packages, it 
looks ok with exception of some warnings (-fglasgow-exts, for example). 
But the package stream-fusion could not compile, because it's cabal file 
has an illegal ghc option: -fno-method-sharing. I commented this out and 
then everything worked fine.
