Comment (by dubiousjim):

 I think I have a similar issue, but I can open a new ticket if
 appropriate. I'm trying to install `openmpi-clang90`, but I get the same
 error reported above. Error persisted when I built using
 `configure.cxx_stdlib='libc++'`, and/or built using the `+g95` variant
 (the `+gfortran` variant doesn't seem to be available anymore on either
 `openmpi-clang90` nor on `openmpi-default`), and/or attempted to install
 `openmpi-clang80` or `openmpi-default` instead.

 If I cd into the work directory and enter the configure command manually
 (`sudo
 /opt/local/var/macports/build/_opt_local_var_macports_sources_rsync.macports.org_release_tarballs_ports_science_openmpi
 /openmpi-clang90/work/openmpi-4.0.1/configure --prefix=/opt/local
 --enable-mpi-fortran --enable-mpi-cxx FFLAGS='' F77=''
 --bindir=/opt/local/libexec/openmpi-clang90 --libdir=/opt/local/lib
 /openmpi-clang90 --sysconfdir=/opt/local/etc/openmpi-clang90
 --includedir=/opt/local/include/openmpi-clang90 --datadir=/opt/local/share
 /openmpi-clang90 --docdir=/opt/local/share/docdelete
 --mandir=/opt/local/share/mandelete --with-hwloc=/opt/local`) it completes
 successfully. But then it's using `gcc` for `gcc` instead of
 `/opt/local/bin/clang-mp-9.0`).
