against 2.6.9rc1[2].

Since buildout is still building Python 2.6.8 we should use a URL to a
version of the patch that applies to 2.6.8.

Add BUILDOUT_HOME to specify alternate configuration source.

unzipped setuptools egg is acceptable.

The source code maps `macosx` to `'darwin' in sys_platform`, so this is definitely Mac OS X and not the *old* Mac OS.
