glshim: Unable to run glxinfo/glxgears

I’ve been trying to get glxinfo and/or glxgears to run when using glshim (on a Nokia N900).

My ~/lib directory has tinygles in it as well, so I am explicitly setting LIBGL_GLES to system libGLES binary so that it doesn’t get used in this test.

If I set LIBGL_GL, as you suggest in some other issue threads here, I get a segfault with glxinfo:
