simple directions to install gtk haskell libs on OS X lion so that Everything works

gistfile1.txt

note that these directions probably can use some cleanup, but i'm choosing these steps so that rebuilding any haskell library doesn't require remembering ANYTHING :-)
(tested on ghc 7.2.2, assumes you have standard developer things installed on mac, like x11 and stuff)

1) cabal install gtk2hs-buildtools  #(this should work with any haskell platform install)

2) brew install cairo gtk gettext fontconfig

3) brew link cairo gettext fontconfig # brew will complain, who cares, this makes your life easier (at least if you're living in a haskell world :p )

4) download libfreetype, heres a URL you can use http://sourceforge.net/projects/freetype/files/freetype2/2.4.8/freetype-2.4.8.tar.bz2/download?use_mirror=iweb
5) unpack libfreetype, and then run 
./configure ; make ; make install
this will install the static and dynamic library files for lib freetype in /usr/local/  (../include and ../lib) , which is what you'll want, though this will contribute to brew doctor complaining, but again, this is the easiest way

6) cabal install gtk

this should work sans complaints!

now you can eg 
cabal install chart-gtk  
and run 
this https://gist.github.com/1655252 example chart code either by building with ghc and running the executable
or by running main in ghc, and 
or
try out some other cool libraries like diagrams!
