cabal install ghcjs-dom

setup: The pkg-config package 'webkitgtk-3.0' version >=1.8 is required but it
could not be found.
cabal: Error: some packages failed to install:
ghcjs-dom-0.2.3.1 depends on webkitgtk3-0.14.1.1 which failed to install.
webkitgtk3-0.14.1.1 failed during the configure step. The exception was:
ExitFailure 1

I've tried the following commands to install this sucker:

brew install gtk+3    
brew install webkitgtk
brew install webkitgtk3
brew install webkitgtk+3
cabal install webkitgtk3

...but no such luck. does anyone know how to install this package?

As I'm still running into this problem now, I've created a repository here with an attempt at a homebrew tap to solve this problem. It's not fully functional yet but I think it's close.
