gnash, FreeBSD and OpenGL -- usable?

[Oliver Iberien]

I've just installed the latest port (0.7_1) of gnash. Trying to run it, I get 
this:

$ gnash

(gnash:69101): GdkGLExt-WARNING **: Window system doesn't support OpenGL.
$

Is there a fix for this? (And if there is, are there more issues to face after 
this one is dealt with?) I know it is still early days for gnash.

Thanks,

Oliver
