Trouble installing py2cairo on Mac OSX Lion

Question

I have spent the last several nights trying to install py2cairo on Mac OSX Lion using gcc-4.2 and Python2.6, attempting a number of the approaches mentioned in these links (among many others; as a new user, I can post only two links):

How to install PyCairo 1.10 on Mac OSX with default python

Unfortunately, I'm still running into a problem with the wrong header files being found. See below for my environment settings and the error output from waf build. I'd greatly appreciate any pointers. Thanks!

If you haven’t solved this yet, try cairocffi: http://packages.python.org/cairocffi/

In case anyone is still have issues with py2cairo on OSX. I was able to get running by using install_name_tool. The config/build process was working and finding the correct version of python. However the compiled binary was linked against the incorrect version of python. This appears to be a bug in waf build system.

To fix the problem...

$ cd /usr/local/lib/python2.7/site-packages/cairo
$ otool -L _cairo.so 
_cairo.so:
    /Users/charlie/Downloads/py2cairo/build_directory/src/_cairo.so (compatibility version 0.0.0, current version 0.0.0)
    /usr/local/lib/libcairo.2.dylib (compatibility version 11403.0.0, current version 11403.2.0)
    /System/Library/Frameworks/Python.framework/Versions/2.7/Python (compatibility version 2.7.0, current version 2.7.6)
    /usr/lib/libSystem.B.dylib (compatibility version 1.0.0, current version 1213.0.0)
$ sudo install_name_tool -change /System/Library/Frameworks/Python.framework/Versions/2.7/Python /Library/Frameworks/Python.framework/Versions/2.7/Python _cairo.so 
$ otool -L _cairo.so 
_cairo.so:
    /Users/charlie/Downloads/py2cairo/build_directory/src/_cairo.so (compatibility version 0.0.0, current version 0.0.0)
    /usr/local/lib/libcairo.2.dylib (compatibility version 11403.0.0, current version 11403.2.0)
    /Library/Frameworks/Python.framework/Versions/2.7/Python (compatibility version 2.7.0, current version 2.7.6)
    /usr/lib/libSystem.B.dylib (compatibility version 1.0.0, current version 1213.0.0)

You can then import and use cairo in the version of python that you ran the waf script with.
