cabal doesn't include c header files

I just installed the most recent version of the Haskell Platform (2011.something) on Mac OS X 10.6.7.

I seems that cabal doesn't include c header files properly.

E.g. when attempting to install cryptohash i get the following error:

How do i fix this?

Just to lock the answer in: this is a bug in a version of the Haskell Platform related to XCode 4. http://trac.haskell.org/haskell-platform/ticket/163
