Comment (by kencu):

 it looks like hdf5 doesn’t build c++ by default…

 https://github.com/macports/macports-
 ports/blob/master/science/hdf5/Portfile

 have you manually added the experimental c++ variant?

 https://github.com/macports/macports-
 ports/blob/818e6a772d912d74344f887f0a500e68feacb38f/science/hdf5/Portfile#L127

 I don’t see a c++ standard set in the portfile, so there could be issues
 if other ports that use the library do set one.

 basically, libraries, and consumers of libraries, generally need to use a
 matching c++ standard.
