is there a Fortran-90 compiler port? Where to get a FOSS Fortran-90 compiler?

Yes, that is it.  Macports implementation decided to decorate the name of
the executable.  There is no naked "gfortran".  It is gfortran-mp-12,
gfortran-mp-13, etc.  This way you can have multiple versions installed
side by side, if you wish.  For convenience, I usually sym link "gfortran"
to the latest MP version.
