Solved

yum install kernel-devel didn't work because like a moron, I was in smp
kernel and so I needed to yum install kernel-smp-devel which then made
it all work but of course the boot cd is a uni-processor so I will have
to wait until I can reboot the production machine into a uni-processor
mode to compile a suitable module to test
