Comment:

 Well, per issue:62878 and issue:62887, it's desirable to block known build
 failures. Otherwise the buildbots waste time on ports that we know will
 fail.

 > Every version of gcc builds all the way back to Tiger. I know MacPorts
 has turned off the builds of gcc8+ on older systems presently. There is no
 good reason for that, except that I just haven't got round to fixing that
 yet.

 Sounds like you have some work to do then.  ;-)

 Of note, `openmpi` will build via Xcode clang, as well as gcc7, without
 restriction. So that's one potential alternative.
