Hi
/proc/cpuinfo tells me I have 4 CPU's and each is Intel(R) Xeon(R) CPU X5460 @ 3.16GHz which file under CONFIG/ARCHS should I use?

My guess is that configure doesn't recognize the chip due to changing model/CPU family values. What does your full cpuinfo look like? >From what wikipedia shows me, this is a Core2-based processor, so you should be able to compare against Core2Duo64SSE3.tgz. If you want to try to install using the Core2 architectural defaults, pass : -A 15 to configure. For Core2-based systems, you will get substantially better double precision performance with 3.9.1 than you do with 3.8.2 (from the above, it looks like you are using 3.8.2).

Great for you. How about the output of cpuinfo for me?
