Ah. I'll probably push out a fix tomorrow then and you can grab that.

You should be able to simply cabal install haddock as long as you are
using the GHC version it expects. For Haddock HEAD (to-be 2.15.0), you
need GHC 7.9: you can just go to utils/haddock in the GHC tree and run
cabal install there (or clone outside of the tree or whatever). For the
2.14.x releases, we require 7.8.x.
