[GRASS-dev] compilation success

[Michael Barton]

With William's recent fix, I got farther tonight on getting a working  
wxPython nviz than ever before.

I still have to remove render.c, but otherwise compilation goes well.  
When I select nviz from the map display, I now get a message box  
saying "Please wait, loading data..." and I get a partial nviz toolbar  
(color picker and exit door). Then it sits. In the layer manager  
output window, I get the following error.

===============

===============

Looks like it may be stuck on a bad wxPython widget definition.
