It returns the error listed in the commit message "ERROR: Problem encountered: building dri drivers require at least one windowing system or classic osmesa" during configuration. Ross and I talked about it and he said this was specific to X11 implementation and wasn't meant to work for other implementations. (fbdev/QT/etc.) If Wayland is supposed to work, then someone needs to go in and adjust the configuration to also support Wayland. I don't have any Wayland systems to even know what the right configuration COULD be. The specific configuration I'm running has "OpenGL" in the DISTRO_FEATURE, but does NOT have X11 or Wayland".
