An idea. Perhaps this will help narrow it down. From within the
ubuntu11 on virtualbox:
Xvfb :5 -screen 0 800x600x24 &> xvfb.log &
cgalpngtest sphere.scad out.png
this will create a Xvfb fake x server on :5. when cgalpngtest runs it
will connect to :5 (thanks to DISPLAY env var), and connect to the
xvfb server instead of to ubuntu's X server under virtualbox.
If that works, it might help narrow the problem down
