The NVIDIA binary drivers replace all OpenGL libraries.

They have to bring the same symbols, so I don't know why "eglMakeCurrent in -lEGL" fails. Maybe they
split the libraries and used different dependencies to work correctly. I guess configure just uses
objdump to look for the symbol, which won't (can't?) follow depending library chains.

My suggestion would be: use schroot and build LO in a clean environment. My build schroot is ~3GB
size. That way the LO build won't interact with your main system and you should be able to still use
the NVIDIA binary driver on the host.
