[GRASS-dev] wxpython 3 and errors in grass

There is a GRASS_WXBUNDLED var (set in the OS X grass.sh) that globalvar.py checks for, to avoid the CheckForWx() call, and it's wxversion stuff.  I think the problem was that the bundled wxpython would be ignored, even though it was before another installed wxpython in the search path, something to do with the wxversion mechanism for selecting a version.

We then bundle all wxPython code into the binary *.app and GRASS uses that, whatever wx is on the user’s system. Perhaps you can’t do something similar in Linux.
