You mean from FreeBSD ports, specifically, right?  I've always been able
to run up-to-date Modula-3 on FreeBSD but it's been a bit of a hassle
installing things (from DECSRC, Polytechnique de Montreal, or elego).
Having it in ports definitely makes things much much easier.

Peter's following email suggests we "just" need an upgrade.

Otherwise the procedure is, if I remember right, to change a flag in
m3core/threads, rebuild m3core, then rebuild the compiler, then rebuild
everything else.
