It's been a while since I worked on it, but a few things to bear in mind:-
- OpenGL ES 1.x is not supported (and never will be)
- configure detects OpenGL ES 2.0 support based upon the presence of GLES2/gl2.h
- from memory, that header is provided by a mesa package (unless you
manually add it and a few others)
All of my testing was done either using the nvidia proprietary driver
with the PVRVFrame emulation library or directly on an early
