/usr/bin/ld: cannot find -lGL

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

Odd:

[root at lri-105689 rgl]# /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) => /lib/libGL.so
