If you want hdf5-18 installed with gcc46's fortran and openmpi, do this:

sudo port install openmpi +gcc46 (openmpif90 wraps gcc46's fortran)
sudo port install hdf5-18 +openmpi+fortran (uses openmpi(cc|cxx|f90)
as the compilers)

Similarly for mpich2, but for mpich2, all the gccNN compilers
(c/c++/fort) are used, not just fortran.

This was done to avoid failures when competing gccNN (or lack thereof)
versions were selected for mpich2/openmpi and hdf5-18 +openmpi /
+mpich2.
