Simple script to make existing GHC or HP installation work with Xcode 5

[George Colpitts]

on os 10.9/Xcode 5 with your script on top of os 10.9/Xcode 5 I get the
following errors, not sure if they have anything to do with your script but
before without it I believe I installed Cairo on 10.8/Xcode 4:

 cabal install cairo
