Comment 2 for bug 108629

Thing is solved: see above thread. It appears that libGL.so.1.2 and .1 from an older/other driver version where placed in the /usr/X11R6/lib dir. I think this is due to a single in a distant past when I installed fglrx from the ati-site instead of the one from the repos. See complete information in the thread itself on page 2
