I had the same problem. It turned out to be that for some unknown reason I ended up with:
/Library/Haskell/ghc-7.8.3-x86_64/bin/cabal -> cabal.wrap /Library/Haskell/ghc-7.8.3-x86_64/bin/cabal.real -> cabal.wrap /Library/Haskell/ghc-7.8.3-x86_64/bin/cabal.wrap
where cabal.wrap is a shell script that checks if a new cabal.config should be created and then calls… cabal.real. Replacing cabal.real with a binary version of cabal solves it.
I don’t know why this happened, I suspect that it might occur if you had ghc 7.8.2 already installed...
I believe this is a bug in the scripts activate-hs and uninstall-hs provided by the Haskell Platform installer for Mac OS X. I have reported it here: https://github.com/haskell/haskell-platform/issues/147 -Yitz
