In general, make sure to compile gst-plugins-bad (and libgstgl in
there) without X11/GLX support and only EGL/DispManX support. Then it
will work without X11, and especially the X11 GL support on the RPi is
complete software based and you don't want to use it :)

Can you file a bug about this? Looks like a problem with the build
system for the example application.

Also these. It would have to link with -lbcm_host.
