I installed Python2.7.3 in Cygwin using this guide, I then installed pip from source.
When I try to use pip:
$ pip install sqlalchemy
Downloading/unpacking sqlalchemy

Running setup.py egg_info for package sqlalchemy

Found a guide noting that this happens, and said that running rebaseall should fix this. I tried, and it didn't. I would assume that this is because I did not install python2.7 with the cygwin installer and therefore was not affected by the rebaseall.
UPDATE:
I gave the wrong link to the instructions I used to install python (sorry). I went back and fixed my explanation of what I did...
