 Looks like it is among default ones:
 https://github.com/macports/macports-
 ports/blob/818e6a772d912d74344f887f0a500e68feacb38f/science/hdf5/Portfile#L73
 It might have issues with MPICH though, possibly.

 What would be a solution to try? Set cxx_standard 2011, rebuild and see if
 that solves the issue?
