Well that is odd. It means that the linker cannot find libGL even
though it is installed on the system. Try 

/sbin/ldconfig -p | grep libGL.so

You should see something like this.

[martyn at braque-iarc-lan minutes]$ /sbin/ldconfig -p | grep libGL.so
	libGL.so.1 (libc6,x86-64) => /lib64/libGL.so.1
	libGL.so.1 (libc6) => /lib/libGL.so.1
	libGL.so (libc6,x86-64) => /lib64/libGL.so

If you don't see the entry pointing to /lib64/libGL.so then type

sudo /sbin/ldconfig

and try again.
