Comment 12 for bug 160766

I already have a link to libGL.so:

$ sudo ls -l /usr/lib/libGL.so*
lrwxrwxrwx 1 root root 10 2009-12-05 16:26 /usr/lib/libGL.so -> libGL.so.1
lrwxrwxrwx 1 root root 18 2010-03-24 09:04 /usr/lib/libGL.so.1 -> libGL.so.185.18.36
-rw-r--r-- 1 root root 792992 2009-10-26 06:16 /usr/lib/libGL.so.185.18.36

And I rebuilt the ld cache, just to be sure:

$ sudo ldconfig

But the 3D Chess View feature still does not work on my system.
