I'm never sure anymore what goes on ros-users and what goes on answers. Specifically answers seems to expect questions, not answers. I felt weird writing a report under the heading "ask a question".
I made some progress in getting rviz to run on OSX, thanks mostly to William Woodall's ogre patch. I wrote a report on
answers.ros.org, for anyone who's interested:
The basic summary is that I got rviz compiled, and as far as the splash screen, when it quit with a segfault.
