Nice, we have a way forward.
With the patch below, I have successfully built:
guix build mumps-openmpi --with-input=openmpi=mpich
and I confirm that despite the name it depends exclusively on MPICH.
:-)
If that’s fine with you I’ll go ahead and commit it; let me know!

We’ll see, but having a solution that works with 3.3 and is likely to
work with 3.4 is good.
I guess we should also check whether we’re obtaining the expected
performance. This builds fine too:
guix build intel-mpi-benchmarks --with-input=openmpi=mpich
Thank you!
Ludo’.
