OK. I now have a puzzle I can't seem to solve.

I have two machines with different software installation histories and
different OS. Various hardware/driver issues preclude my running the
same OS on both. Actually, there's a third machine with yet another OS
version, but I haven't tried running MM 3 on it.

Anyway, on a machine with Ubuntu 13.10 64 bit, I have a virtualenv with
packages up to date, and "python setup.py develop" runs fine and "nose2
-v" runs fine.

On the other machine with Ubuntu 12.10 32 bit, I again have a virtualenv
with packages up to date, and "python setup.py develop" runs fine, but
"nose2 -v" dies immediately with the attached traceback. Both
zope.component and zope.interface are the same version on both machines.
/var/py27 is the virtualenv.
