multimode.py: OpenGL.error.Error: Attempt to retrieve context when no valid context #17

Trying to get gnuradio to work on 10.7.4 Air with an ezcap USB 2.0 DVB-T/DAB/FM dongle.

Using gnuradio with qt-gui, I can hear some (less than perfect) FM audio and can see the various graphs dynamically in real time, but if I try to use multimode.py (which uses wxGui items), after installing installing PyOpenGL-3.0.2b2, it dies with this error message:

% multimode.py Mac OS; Clang version 3.1 (tags/Apple/clang-318.0.61); Boost_105000; UHD_003.004.003-177-g584b7ae2

I am mystified as to how to solve this problem.

Thank you.
