xcode 5 psa info on haskell platform page

george:

here's how to see how broken it'll be :)

cabal get vector-0.10.0.1 ; cd vector-0.10.0.1 ; cabal build

you'll get a nice CPP error at some point in the build cycle there ;)

the issue only surfaces on modules / packages that have CPP, so minimal
testing will show nothing at all :)
