I am attempting to compile an application (MPB from MIT) with support

provides several versions of fftw, but none has support for either
openmpi or mpich2.
Does anyone know of a repo that has fftw with mpi? I have not found
anything on google. I tried compiling fftw from source, but it failed
its own self tests. Besides, installing a home built fftw could affect
other applications that depend on the Fedora-supplied one.
Any suggestion will be appreciated.
File a feature request in bugzilla against fftw.
mpi support hasn't been put in, because compiling even fftw is a mess:
four different flavors are built, consisting of single, double, long
double and quadruple precision.
Plugging in the mpi versions will require 3x4 = 12 separate compiles.
Also, if the flavors are put in separate subpackages, it'll also mean 8
more subpackages...
