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

[George Colpitts]

works for me on os 10.9/Xcode 5 but I did notice a few anomalies. I did
cabal update;cabal install vector and got the following at the end. I also
saw a similar message when I did cabal install bytestring.

Preprocessing library vector-0.10.9.1...
