install gtk2hs with Darcs

Question

I'm having some existing code that I'm not able to run without gtk2hs. But I can't get it installed. I tried with cabal before but found out that the correct solution for now is to build from darcs. So I do :

darcs get --lazy http://code.haskell.org/gtk2hs
cd gtk2hs
export PATH=$HOME/Library/Haskell/bin:$PATH
sh bootstrap.sh

And get this :

I'm on osx with most recent versions of cabal and darcs.

You must install the gtk C libraries before you install the Haskell bindings to them. Visit the installation instructions and check the section for your operating system if you need instructions on how to do this.
