RHEL6 "Need libwfb but wfbScreenInit not found"

I am following the installation instructions for RHEL6 at http://docs.nvidia.com/cuda/cuda-installation-guide-linux/index.html and I cannot get X to start post-installation.

In /var/log/Xorg.0.log, there is an error that says:

NVIDIA(0): Need libwfb but wfbScreenInit not found

In the docs I found online, it seems that the NVidia installation skips installing a wfb library if one is found, but I do not see one in the X11 module location. How can I fix this problem?

AH, I solved it myself. I needed to install xorg-X11-server-Xorg from RHEL.
