There is no EGL_DEPTH_SIZE in compositor-drm.c

No. Running weston, sleep 2, then simple-egl produces the following 
output (I turned all the debugging environment variables off):

nvfx_screen_get_param:103 -  Warning: unknown PIPE_CAP 57
Mesa 8.1-devel implementation error: Incomplete OpenGL ES 2.0 support.

The display is still black with a tiny icon in the corner. Clicking the 
icon produces:

There was only "/* #undef HAVE_CAIRO_EGL */" (ie an undef commented out) 
in config.h. I un-commented it, did make clean, make, sudo make install. 
The result is the exact same error message as before.

Thanks. I turned off the environment variable in wayland-run.sh
