I did nothing special to make it work. I'm also using the standard system python 2.6.1. I did a build and it worked fine. I posted my binaries for students and colleagues. A student downloaded it and it won't run. She has a very similar machine.

Sorry I'm no help. I think it is something else wrong and that this error is probably not what is really wrong.
