I am still trying to track this down.

I suspect that part of the reason is that macports updated its default
gcc compiler from gcc8 to gcc9 which may cause this.

I can reproduce the problem on my MacPorts VM test setup but it being
very slow have not been able to test it fully.

Reading the ports file
https://github.com/macports/macports-ports/blob/master/science/openmpi/Portfile it would seem as if builds using gcc should contain the fortran bindings.

I would try;

sudo port uninstall gcc8
sudo port install gcc9 openmpi-gcc9

then try and see if

sudo port select --list mpi 
 
Yours,
Roland
