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

I resolved this by reinstalling mesa-libGL (dnf reinstall libGL) seems
/lib64/libGL.so.1.2.0 was missing off the disk.

Thank you!

Any chance that you have the NVIDIA driver in play here? They monkey
around with libGL.

EXACTLY!!! I use the NVidia drivers from their site, and that is exactly what
happened. I reinstalled mesa-libGL.x86_64 and that resolved the issue (though
not sure if that broke anything else on the workstation that relies on the
NVidia drivers)
