[ale] CentOS 7 and NVIDIA

[Jim Kinney]

SOLVED!

The kmod-devel package needed to be installed so the NVIDIA binary blob
mess could be compiled for the kernel.

I also installed several of the F19 rpms related to akmod in the testing
process and they installed with no errors. Nice to know the overlap is
there.

Every time you stop a school, you will have to build a jail. What you gain
at one end you lose at the other. It's like feeding a dog on his own tail.
It won't fatten the dog.
