getting py2cairo installed on osx w/ brew

(this is more of an gist that a post)

The configuration failed
(complete log in /Volumes/HDD/Downloads/py2cairo-1.10.0/build_directory/config.log)

 After a TON of trial and error, followed by brew install , here's what I came up with: 
 export PKG_CONFIG_PATH=/usr/X11/lib/pkgconfig:/usr/local/Cellar/libpng/1.5.13/lib/pkgconfig:/usr/local/Cellar/freetype/2.4.10/lib/pkgconfig:/usr/local/Cellar/fontconfig/2.10.1/lib/pkgconfig:/usr/local/Cellar/pixman/0.28.0/lib/pkgconfig:/usr/local/Cellar/cairo/1.12.8/lib/pkgconfig:/opt/local/lib/pkgconfig
