Details:

Trying to build without opengl (so that documentation doesn't fail and an
installation can be done):

$<path_to_base_dir>/configure --without-opengl; make install

, I've found there are some unprotected portions of the Open GL code or this
file libinterp_corefcn_libcorefcn_la-gl-render.cc is mistakenly being built by
the system when it shouldn't:
