I happened to get to a similar state after upgrading from OS X Lion to Mountain Lion today.

The other proposed solutions either do not work, or replace the Apple version of Python with the brew version, which I'm not sure is what saclark asked for.

What I did to get it fixed is install distribute manually, thus getting easy_install back to work, and then install pip with it.

The commands are:

$ curl -O http://pypi.python.org/packages/source/d/distribute/distribute-0.6.45.tar.gz
$ tar -xzvf distribute-0.6.45.tar.gz
$ cd distribute-0.6.45
$ sudo python setup.py install
$ sudo easy_install pip

If the link does not work, you can alway find newer versions of distribute here.
