separating SSH from FFTW

While reviewing what processes my desktop environment (XFCE4) starts, I discovered that it starts `ssh-agent`. Since I don't use SSH, I investigated. The media player `mpv` requires `openssh` via the following chain: `mpv` → `rubberband` → `libfftw3.so` → `openmpi` → `openssh`. An SSH implementation is required for OpenMPI support in FFTW. However, `rubberband` does not use the FFTW `.so` libraries `libfftw3*_mpi.so` that use OpenMPI. As I understand, OpenMPI is needed only when computing on clusters. I guess that the number of people using `mpv` is much higher that those having computational clusters. Can we, please, have FFTW/OpenMPI libraries as a separate package?

Re: separating SSH from FFTW

What if openssh was moved to optdepends instead of splitting the openmpi package.  Would that not achieve the same result?

Probably, you are right. I am not very familiar with the rules. It's all the same to me. People using OpenMPI may have their opinion. Let's hear them.
