I've always skipped GLCanvas on my Windows build, so I don't know 
exactly what's up. I'm guessing some missing library i.e. opengl. Sean 
makes the release windows build so may have some ideas.

If you don't need GLCanvas, probably easiest just to avoid it.

Method 1) This should force wxRuby to skip this class, but you'll need 
to remember this argument every time, or set an environment variable. 
Delete src/GLCanvas.cpp then build wxRuby with:

rake WXRUBY_EXCLUDED=GLCanvas

Method 2) Rebuild wxWidgets without the USE_OPENGL argument to nmake. 
Then wxRuby should notice that class isn't supported and skip it.

Yeah, we upgraded to the latest SWIG releases in the dev cycle as they 
have ruby fixes pertinent to wxRuby. The code was already checking, but 
I've updated the wiki to reflect this. Thanks
