Strange... does your GL support ARB_imaging?  It is safe to hack out the 
glBlendEquation lines (subtractive blending won't work correctly) but it 
should be guarded by GLEW_ARB_imaging.  You will also have to disable it in 
the RAS_OpenGLRasterizer constructor.
GLEW_ARB_imaging = 0;
should do it.

According to the GL headers, glBlendEquation might be a 1.4 function.  (There 
is no ARB_imaging reference)

Alternatively, replace all glBlendEquation with glBlendEquationEXT and 
GLEW_ARB_imaging with GLEW_EXT_blend_subtract.  This is probably the correct 
fix, and I'll commit it when CVS comes back up.
