Hi,
Before I could compile it I needed to modify the portfile as per  https://trac.macports.org/ticket/46228

I've attached the modified portfile for your reference and convenience.

A simple insertion of -latlas did the trick e.g.
configure.args      --without-omniORB --disable-python-interface --disable-modelica3d --disable-omnotebook --with-lapack="-llapack -lblas -latlas" --without-omc --without-omlibrary

I hope to now enjoy your excellent software.
yours
G
Portfile.
