What command produced that output?

It's hard for me to know whether that indicates you're using MacPorts Python 2.7, or possibly Apple Python 2.7, if that's the version of Python that's on Lion.

Exactly how are you running your code? i.e. by typing "python" (in which case, what does "which python" say?), by typing python2.7, by typing /opt/local/bin/python2.7, etc.
