Simultaneous openmpi and mpich is (if I recall) down to some man page
conflicts. (Openmpi is renaming their bins, but not the associated mans.)

Re:fortran, how would you propose 'mpich +clang' (for example) address
Fortran? I personally use mpich (cc/ccx) extensively without Fortran;
should I be required to install a fortran compiler & wrapper I don't need?
If installed with a +gcc variant (and therefore a fort compiler is present)
mpich enables fortran.

I'm dead set not against it, but I suppose I need some convincing.

Thanks,
