It may be a clang issue with not implementing/using -Wno-error,-Wimplicit-fallthrough ?

As far as I can tell FC_VARIABLE was added in fontconfig 2.13.1 so it should exist. What version of fontconfig do you have installed? Try running:

port -v installed fontconfig
/opt/local/bin/fc-cache --version

The version currently in MacPorts is 2.14.1.

Please always attach the main.log file when you file a bug report.

It may be a clang issue with not implementing/using -Wno-error,-Wimplicit-fallthrough?

That doesn't matter here. -Wno-error,-Wimplicit-fallthrough instructs the compiler that, if it generates an implicit fallthrough warning, it should not consider that to be an error. In response, your compiler has warned you that it cannot generate an implicit fallthrough warning, which is fine.

This is not similar; not related to this ticket. This is a bug in g-ir-scanner, which is part of the gobject-introspection port. It has been an ongoing problem with gobject-introspection for years; the developers of that software have not responded to our bug report about it. See:
