Found an answer. See my answer below (guess I can't accept my own)

Setting up things on my (gentoo) desktop.

Command line output just about says everything:

$ rosrun rviz rviz
Failed to initialize Ogre: OGRE EXCEPTION(7:InternalErrorException): Could not load dynamic library RenderSystem_GL.  System Error: RenderSystem_GL.so: cannot open shared object file: No such file or directory in DynLib::load at /home/murph/ros/visualization_common/ogre/build/ogre_src_v1-7-1/OgreMain/src/OgreDynLib.cpp (line 91)
[ERROR] [1298662054.238455770]: Caught exception while loading: OGRE EXCEPTION(7:InternalErrorException): Could not load dynamic library RenderSystem_GL.

murph@murph ~/ros $ find . | grep -i RenderSystem_GL.so
./visualization_common/ogre/ogre/lib/OGRE/RenderSystem_GL.so
./visualization_common/ogre/build/ogre_src_v1-7-1/build/lib/RenderSystem_GL.so

My hardware: 01:00.0 VGA compatible controller: ATI Technologies Inc RV620 [FirePro 2260]

And my drivers: x11-drivers/xf86-video-ati version 6.13.1

[edit] I found this: https://code.ros.org/gf/project/ros/m...

Which sounds similar. I copied RenderSystem_GL.so, Plugin_OctreeSceneManager.so, and Plugin_ParticleFX.so up a folder as indicator (one by one as they were pointed out as missing), but now it cannot find Plugin_CgProgramManager.so which I do not have anywhere.

[edit 2] When doing 'make' after 'make wipe' on the ogre subtree, I see this:

-----------------------------------------------------------------------------

Notice that cg is included there. So perhaps the configure scripts can't find my Cg libraries (they are installed)? I'm no cmake wizard, though.

Could you update your question to include your graphics card and driver version.

Looks like the ogre setup doesn't search the right locations for you Cg libraries on Gentoo. Set this before you run make wipe && make in the ogre subfolder.

export Cg_HOME=/opt/nvidia-cg-toolkit
Also, it seems that for some reason gentoo systems end up putting some of the .so files in the wrong folder, so we'll need to move them afterwards.
export Cg_HOME=/opt/nvidia-cg-toolkit 
cd ~/ros/visualization_common/ogre       <-- obviously change this location if required
make wipe && make
rosmake rviz
cp ogre/lib/OGRE/*.so ogre/lib/
rosrun rviz rviz

Of course, now it segfaults. But I'm sure that's something different.

Also look at this answer. There are some path issues in plugin.cfg in the default setup: http://answers.ros.org/question/3500/rvizrviz_qt-ogre-dynlib_load-mac-lion

IIRC, I was getting a similar error compiling rviz on my Mac, and installing Cg seems to have fixed it. I think Ogre may configure itself to not build that library if Cg (or maybe some other dependency) is not present, or something.

I have "nvidia-cg-toolkit-2.1.0017" installed.

Looks like a run-time link error. Maybe the library rpath is not getting set correctly? Try 'readelf -d ./visualization_common/ogre/ogre/lib/OGRE/RenderSystem_GL.so', and look for an RPATH line. It should be set to .../visualization_common/ogre/ogre/lib/.

At a second glance it looks like you might not have build ogre. Did you run a rosmake of rviz? And if so try a make wipe && make in the ogre directory and then rerun rosmake rviz

Tried wipe/make/rosmake, get the same thing.
