I'd recommend looking at:
http://www.stackage.org/install#mac-os-x
https://github.com/bitemyapp/learnhaskell/blob/master/README.md#mac-os-x
I don't generally recommend using the platform installer, it ends up
pegging libraries to old versions which causes dependency problems, or in
some cases have known bugs.
