libGL.so != libGL.so.1

Try a symlink between /usr/lib/libGL.so to libGL.so.1

NB: On my box, which is Intel GFX, hence uses the mesa GL drivers:

sudo ldconfig -p|grep libGL.so
	libGL.so.1 (libc6) => /usr/lib/mesa/libGL.so.1
	libGL.so (libc6) => /usr/lib/mesa/libGL.so
	libGL.so (libc6) => /usr/lib/libGL.so
pcjc2@pcjc2lap:~$ ls -l /usr/lib/libGL.so 
lrwxrwxrwx 1 root root 13 2010-04-14 17:57 /usr/lib/libGL.so -> mesa/libGL.so
