Hmmm. I can reproduce this error when calling the command from
terminal (it works inside Qt though). I'm not sure if the reason lies
in the lack of some backends (you could try to compile geant4 with
+opengl_x11 for example – Gate will probably need to be recompiled,
but I'm not sure) or if it's some "bug" in Gate (or maybe even in
Geant4).

It shouldn't have happened. And once you have "Gate --qt" working,
this won't be an issue.

But it would be nice if one of developers could look into it. I'll try
to see if installing X11 helps in any way.

You can work around the problem in the way that Marc described it. I
would really like to see the upstream sources to be fixed, but if
nobody from the Gate development team answers withing a few days or if
you need assistance applying the patch, I'll change the Portfile.
