Wonderful, thanks a lot for your help! It seems to work now. For
future reference:
Now I know that pygame and OpenGL work fine on this machine (at least
for two simple games I found online that use both), despite the
cryptic error.
And adding
VisionEgg.config.VISIONEGG_GUI_INIT = 0
VisionEgg.config.VISIONEGG_GUI_ON_ERROR = 0
right after the "import VisionEgg" seemed to do the trick and get my
old vision egg scripts to run. Now to add extra config options for
full screen, etc...
And as long as we're at it, since I am a newbie and couldn't figure
out how to use macports very productively (and expect that other
people might run into the same issues), could someone post some of the
actual commands that are necessary? I managed to find "port install
py26-game", but this was unintuitive in regards to the version
selection. Maybe we could compile a step-by-step for ignorant folks
such as myself.
Thanks!!!
Geoff
