Thanks Brian and Jack for the quick replies. I actually followed the directions from the site with the workaround and Stage still won't run. Then I copied rgb.txt into a whole bunch of locations suggested in the forum below the bug report and it still won't work. I just upgraded one of my jaunty machines to karmic, downloaded the newest ros-cturtle-pr2all binaries and I'm still getting the same error. I'll go ahead and try putting rgb.txt in /etc/X11 to see if it fixes on karmic.
