My guess is that some logic in the spec file is getting your running
kernel wrong ...

Install the SRPM and have a look at the spec file - my guess it is
doing some sed'ing, awk'ing or grep'ing on the kernel version and it
getting wrong - may be it doesn't support 'largesmp' ??

I suggest you use the 'normal' smp kernel - I believe the largesmp
kernel is for machines with 8 or more CPUs/cores
