This would be one possibility, indeed. Though X has become rather sophisticated
about auto-detecting GL which would make we wonder a bit. I presume that
some library is missing.

Is the game neverball working for you? Does that install libgl1-mesa-glx | libgl1
or is it allready installed? What about BALLview, does that start?

Please give those programs a try and if they work then try rgl again. If the
error persists then this will certainly cause some head scratching. If not,
then the dependencies are incomplete.

Best,
