AFAIK, it was $ sudo apt-get --no-install-recommends install libgl1-mesa-dri
when I wanted to run Minetest on the MiniRuben should incorporate many missing (basic) features into the Mini edition (as I suggested during the development), because the default installation is barely usable for an average person without making heavy modifications. Maybe the initial goal of providing a 500MB disc image should be reconsidered to be increased onto 700.
