Comment (by george.colpitts):

 Thanks, sounds like we are all set. Sorry for any confusion I may caused.

 "The problem" is a bit ambiguous. I was referring to the first of the 3
 issues mentioned: gcc is no longer available and the clang compatibility
 patches of ?http://ghc.haskell.org/trac/ghc/ticket/7678 are not included
 in 7.6.3. After downloading Xcode 5 onto 10.8 I was unable to install the
 random-fu package getting errors that seemed the same as those mentioned
 at ?https://github.com/mxcl/homebrew/issues/20546, particularly those of
 dhess "GHC uses the system's C preprocessor, and Clang can't parse CPP
 directives that split lines. A similar problem occurs when compiling
 certain Haskell libraries (e.g., cereal) on 10.8 using the Xcode 5 DP and
 Homebrew-installed GHC."

 > Actually, no. This patch fixes problems that occur when building on 10.9
 regardless of whether GCC or clang (Xcode 5) are used. In other words,
 it's not related to Xcode 5 at all.

 > Building GHC on 10.8 with Xcode 5 does not require this patch. I've
 already tested this to make sure.
