It does, and it's indeed a python3 binary. At least now I see the
culprit.  If I wipe out PYTHONPATH and start that python, here's the
sys.path it sees:

>>> pprint(sys.path)
['',
 '/home/fperez/.ipy_pr_tests/venv-python3.2/lib/python3.2/site-packages/distribute-0.6.24-py3.2.egg',
 '/home/fperez/.ipy_pr_tests/venv-python3.2/lib/python3.2/site-packages/pip-1.1-py3.2.egg',
 '/home/fperez/.ipy_pr_tests/venv-python3.2/lib/python3.2/site-packages/ipython-0.13.dev-py3.2.egg',
 '/usr/lib/pymodules/python2.7',
 '/home/fperez/.ipy_pr_tests/venv-python3.2/bin',
 '/home/fperez/.ipy_pr_tests/venv-python3.2/lib/python3.2',
 '/home/fperez/.ipy_pr_tests/venv-python3.2/lib/python3.2/plat-linux2',
 '/home/fperez/.ipy_pr_tests/venv-python3.2/lib/python3.2/lib-dynload',
 '/usr/lib/python3.2',
 '/usr/lib/python3.2/plat-linux2',
 '/home/fperez/.ipy_pr_tests/venv-python3.2/lib/python3.2/site-packages',
 '/home/fperez/.local/lib/python3.2/site-packages',
 '/usr/lib/python3/dist-packages',
 '/usr/local/lib/python3.2/dist-packages']

That '/usr/lib/pymodules/python2.7' in the middle is what's messing
things up.  I wonder what in this Ubuntu box is setting that
variable...  It's not anything in my personal environment, b/c that's
all just PYTHONPATH.  It's as if a system-wide config file is getting
picked up somewhere...

Frustrating.
