Comment (by George):

 Not sure if this helps, but with Xcode 5,  Mavericks, the latest Haskell
 platform after running Mark Lentczner script (emailed Oct. 31 to haskell-
 platform at projects.haskell.org,haskell-cafe at haskell.org, and ghc-
 devs at haskell.org) I am able to compile happy 1.19.1:

 cabal install happy
