AFAIK there is no special trick to compile pw.x; just compile
for either v.2 or v.3 of FFTW and load the mkl wrappers,
provided by Intel as a separate package, to be compiled.

I heard that the FFTW v.2 wrappers work for both serial
and parallel execution, but you gain little; you gain much
more with v.3 wrappers, but they work only for the serial
case.
