It looks like a communication issue between hdf5 and mathgl then: hdf5
makes mathgl include mpi.h (H5_HAVE_PARALLEL), but does not seem to
provide it with what is necessary for it (CFLAGS). Report the bug and
discuss with the maintainer how that is supposed to work.

Try to reproduce on Linux, now that it uses openmpi, you should be
having the same issue. If not, compare and see what's different.
