Open GL dependencies

I've got a kivy project that would work well with x2go.  Running the
program in a normal window works with open GL being reported as OpenGL
version <2.1 Mesa 8.0.4>

but when running on linux via x2go it reports as <1.2 (1.5 Mesa 6.4.1)>
before segfaulting.  Kivy apparently needs a newer open GL version.

Can anyone give me, ANY, hints as to where I should go looking.  
Thanks,

Paul Daniels
