[Haskell-cafe] How to install GhC on a Mac without registering?

I rarely use a Mac because it is too cute, but I bought one for my wife. I'd like to install GHC on her Mac just to test Haskell Platform and cabal install. (I rarely use Windows too, but testing GHC & cabal install is completely painless.) To do a quick test, do I really have to register as an Apple developer, or is there a way to test the platform anonymously? Someone who some times worries about privacy, John
