## NB 2012-10-23: the reason we are fetching the git repo is that
## my vague belief that 0.90.1.0 doesn't work with the GHC or
## Haskell Platform version we want (I may be wrong).
##
## If a newer release comes out, we should replace this with just
## plain old 'cabal install wx'
#git clone https://github.com/wxHaskell/wxHaskell.git
#pushd wxHaskell
##git checkout 2f065e5348343ab95ad3f1465af2619d31bcdf37 # known working version
