Hmm. Once updated, my system shows:

$ ldd -r /usr/lib64/libGL.so
	linux-vdso.so.1 =>  (0x00007ffe9a9fb000)

Please could you show 'rpm -qf /usr/lib64/libGL.so' and 'll 
/usr/lib64/libGL.so' - is it symlinking to the nvidia LibGL.so library? 
As you're still using the old nvidia packages, it should symlink to 
/usr/lib64/nvidia/libGL.so.1

But before we get too deep into this - does updating the nvidia packages 
fix the issue? If yum still isn't finding them, can you download and 
manually update?

I found this bug, maybe related:
