Strange behavior, my gimp.app automatically launch X11 :)
Can't remember how i set up this !
OK - I've never tried GIMP on OSX, but I have had trouble calling X11
apps w/o running X11 in the past. Still, it may not be installed - I
don't think it was installed by default in 10.3...
Roger - make sure you have X11 in apps>utilities>X11
