Obviously the needed libraries are installed, otherwise you would not have an executable. And it doesn't seem to have unresolved symbols in shared objects when startting mini.
Now from the error message:
"OpenGL Warning: XGetVisualInfo returned 0 visuals"
it seems OpenGL doesn't find any device to display on.
The back-end of OpenGL is dependent on your OS and your graphics hardware and virtualization layers.
Like most graphics-related issues, these are difficult ones.
By googling the above message, it seems correlated to VirtualBox and its configuration.
No clue of any other OpenGL example / test for Linux. Anyone ?...
