Comment (by majoc-at-astro):

 I have a partial workaround (of which I'm not proud), with which our build
 scripts fail to fail.  Once the resulting armadillo has been tested by
 real users, I'll report back.

 {{{
 hdf5_openmpi_variants="`port installed hdf5 | awk '/active/ {print $2}'`"
 port -f deactivate hdf5
 port install armadillo +arpack # pulls in hdf5 with default variants
 port -f deactivate hdf5
 port activate hdf5 $hdf5_openmpi_variants
 }}}
