I tried to run flightgear 0.9.6 on my freebsd box. It depends on freeglut, simgear, plib ...etc.

I compiled and installed the whole port successfully, but flightgear puts an error on the screen when I try to execute it.

Assertion failed: (window-> Window.VisualInfo!=NULL),function fgOpenWindow, file freeglut_window.c

It seems to be a freeglut problem, that`s why I post it here. There are already a few messages in the mailinglist about it, but nothing that would help me to go on or to fix it.

Any sugesstions?
