Serving suggestion: rather than rip-and-replace, it may be worth using
"port upgrade --enforce-variants offending_port +gcc9 +other_variants"
to change the variants in-place.  We use that trick on a twice-weekly
basis to persuade valgrind +openmpi and openmpi-gcc +valgrind to build
from scratch, as each depends on the other.

Discovering the appropriate values of offending_port, and the matching
values of other_variants for each, is left as an exercise (hint: "port
installed | grep gcc" and variants).  Good luck.
