[GtkGLExt] Help, maybe a bug in FreeBSD 5.3!

[mk mk <mk1g6g yahoo com cn>]

Hello, everyone:

Now I face a problem using latest port of
gtkglext-1.0.6 in
FreeBSD 5.3 release. The problem is I can not
correctly run any example programs. I got following
errors, e.g:

(gears:10449): GdkGLExt-WARNING **: glXMakeCurrent()
failed

The program started normally but the GL drawing area
is blank. and whenever the window need refresh, the
above error showed in the console. My graphic card is
Trident 9397DVD and the system is FreeBSD5.3 + Xorg +
Gnome2.6 (which is the default installation)

This is *not* the problem of OpenGL library of X11,
since I can run the 'glxgears' demo successfully.
So I guess this maybe due to the bug of gtkglext

Thanks a lot
