Installing PyCairo or Py2Cairo on OS X Snow Leopard

Trying to set up PyCairo on OS X Snow Leopard. There are quite a few questions about it on this site, but I'm getting compile errors, which I haven't seen before.

Here are my environment variables...

PKG_CONFIG_PATH=/usr/local/Cellar/cairo/1.10.2/lib/pkgconfig/
PYTHON=PYTHON3

Here's what my WAF config looks like:

TeaMac:py2cairo itadmin$ ./waf configure
  ./options()
Setting top to                           : /Users/itadmin/Sites/py2cairo

'configure' finished successfully (0.580s)

And here's the nastiness of the $ ./waf build step:

Found a solution for this issue on: https://bugs.freedesktop.org/show_bug.cgi?id=37414

Basically, you can work around this by modifying the "build_directory/c4che/_cache.py" file. The problem stems from waf attempting to build for multiple different -arch options. The quick fix - comment out every line that contains '-arch', and your build will succeed.
