As if you didn't already write that in the error message. I was so sure I checked
on that, sorry for bothering you with that. Anyways, I downloaded the Python
source release and simply dropped the /Lib folder into the
/System/..../Frameworks/.../lib/python2.6/ and it works. Is that the correct
way? Seems weird but I'd rather not overwrite the whole python installation.

That's a solution (although usually what I do on Mac OS is getting a python
install from python.org instead of using the default one -- not sure what you
may break in Mac OS if something bad happens there while developing).
