I have done a couple of builds, one with MPI_DIR set to nothing and one with MPI_DIR set to /opt/local. Both build and seem to work. I had replaced the released version of the file detect.pl with the development version. So, the bottom line seems simple: the culprit was the detect.pl.Please let me know if you think my conclusions have issues. Otherwise, I suggest that the dev version of detect.pl be back-ported to the existing Hilbert release. Thus no change is needed in the Hilbert version of osx-macports.cfg.Thanks to all you helped me sort out this.Thanks for noticing the problem! I have created a ticket (https://trac.einsteintoolkit.org/ticket/1794) for the backport. I don't have time right now to do this, but maybe someone else does?
