[R-sig-Debian] revolution mkl with R 3.01 on Ubuntu 13.04

[Elizabeth Tighe]

Dirk,  That worked! Sort of.  It's gone from running processes on one 
processor to two processors and Rbenchmark ran in 64 seconds rather than 
178.  Is there a way to get it to use more than 2 processors when it 
can?  (revo mkl used all available processors by default).

many thanks!
Liz
