Check which kernel you are using - whether smp or not with: $ uname -r and get the kernel development package using yum. If you have an smp kernel use: $ yum install kernel-smp-devel else if you have the regular kernel use: $yum install kernel-devel You should have the sources now that the Nvidia installer needs.
