Kurt,

The hint is the openev in the path.  It turns out if you run openev from
the OSGeo4w command shell it modifies the python path to point to it's
private tree which screws up later normal python stuff.  Just close the
shell and restart it and you should be good.

I have issued an updated version of OpenEV in OSGeo4W that should not
have this problem as the openev.bat restores the PYTHONPATH and
PYTHONHOME environment variables.

Best regards,
