[R] BLAS or ATLAS?

I installed the Intel MLk, 

and tried : --with-blas="-lmkl -lguide -lpthread" 

and got :  External libraries:        readline, BLAS(generic)

thus I'm assuming I'm missing something when telling config where to
look for the recently installed Intel BLAS?

thanks for all replies thus far.
