I didn't mean actually to commit a -py26 option for wxgtk2.8-py , by the
way .  Since the tracker submission was a bit old, I was refactoring it
to exclude -py24 for Leopard and was testing whether -py26 would work,
and it did not, due to opengl-py26 being nonfunctional, as above.

I guess in this case we got a useful diagnostic out of the deal...
