Re: [Visualpython-users] Instructions for building VPython on MacOSX 10.3 and Python 2.3

[Jon S. <js...@so...>]

Good news and bad news

#1:  First, Kevin's instructions were superbly clear and I was able to  
follow them without only one hiccup on a non-clean 10.3 system recently  
upgraded from 10.2.

The hitch came here:

Second, they do seem to have built me a fresh python.  When I type  
visual, I now get

and it works

however (as formerly under 2.2), I still have an OpenGL problem.

at the same time stderr writes

This is apparently unrelated to Python (but I'd still like help!!),  
since I can't run glgears either:

any suggestions??  Might the pango / glib2 hiccup be the issue?
