[R] BLAS or ATLAS?

I'm trying to tweak multi-threading on a multiprocessor box(Xeon).
Reading appendix a.2.2 in the install and admin menu, I see that I can
use the internal BLAS lib and/or a multi-thread version of ATLAS (Where
to get?)

Question: Intel claims their libraries are faster than ATLAS. Has anyone
compiled R against the Intel BLAS? If so...how did you do it? 

http://developer.intel.com/software/products/mkl/features/lin_alg.htm

And I'm in the market for a pre-built Atlas dual processor lib for Xeon.
Know where I can find one? 
Thanks.
