R SIG Debian - Jul 2013 - revolution mkl with R 3.01 on Ubuntu 13.04

So I have two Dell power-edge machines running latest Ubuntu (13.04) 
with latest version of R (3.01).  I installed revolution-mkl on one 
machine (T-410) and it works fine.  On the second machine (T-620), it 
says the latest version of revolution-mkl is installed, but I'm getting 
no multi-processor functioning (R-benchmark-25.R) runs on a single 
processor and takes same amount of time before and after installing.

Both machines I've installed using simple sudo apt-get install r-base 
r-base-dev and same for revolution-mkl

Anyone have any tips for debugging, figuring out why it's not working on 
the second machine?  Is there a way to get R to find the mkl libraries 
without reinstalling from scratch from source code?

Any insights anyone out there might have would be appreciated!

Thanks,
Liz

The revo-mkl package is stale. It was a one-off; its 'closed source but
freely distributed' annoyed a lot of people, and Revo no longer cares about
Ubuntu (or Debian).

Just install libopenblas-dev --- it is also multithreaded, but open source
and under development (as a successor to the not-really-open-source GotoBLAS).
