As probably do all other octave ports. It looks like the octave-using ports are trying to use the compiler that octave was compiled with (on which they don't declare a dependency, which is why it's not there), so they're not UsingTheRightCompiler. So either we cure octave of the misperception that we want that, or we impose the same compiler restrictions on all ports that use octave as the octave port itself imposes (e.g. the cxx11 1.1 portgroup and any additional blacklisting).

In 932adfa747b1f3fb9caeebc989a1b3671570321d/macports-ports (master):

octave PG: respect configure.cxx for linking

Fixes #57419

[MarcusCalhoun-Lopez (Marcus Calhoun-Lopez)]

Thank you for pointing this out.
So this means that many octave-* ports will have to manually rebuilt on the BuildBot server?

[ryandesign (Ryan Carsten Schmidt)]

Sure, I can do that. I'm currently in the process of rebuilding all ports, for the benefit of the new Mojave build worker.
