What version of Python are you using? I wouldn't be surprised if this were a bug in Python 2.7.0 or 2.7.1.

python

I assume "2.7" means 2.7.0. This makes sense since it was released on 2010-07-03 and your build is from 2010-08-07. You'll need to upgrade Python to build the tree. We should probably require Python 2.7.2+ to build the tree and display a very prominent error message if you don't have it installed.

We now require 2.7.3 to build, so this bug has been worked around.
