Comment (by takeshi@…):

 Bill, thanks for letting me know. The problem was fixed by  r126056.

 Sean, I tested {{{mpi.enforce_variant hdf5}}}. It does not seem to check
 whether the variants that are set for hdf5 are also specified on hdfeos5.
 Say

      $ port installed hdf5
        hdf5 @1.8.13_0+cxx+mpich (active)
      $ sudo port -d install hdfeos5

 will not cause error without mpich.
