Comment (by cbrown06):

 @Veence - to answer your question, yes there is a reason, it's to align my
 development environment on macOS with the target Ubuntu 18.04 LTS server
 configuration, which (according to my sysadmin, who prefers to avoid
 installing external APT repositories), "postgis2" is available but not
 "postgis3".

 Even if that would be ideal, I'm open-minded and have considered
 "postgis3"... except that failed for me in the same way:

 Seems like the "postgis3" port has exactly the same problem (I tried and
 can confirm this). I suppose that a fix for "postgis3" would be back-
 portable to "postgis2", but that's just a guess on my part. Even if the
 issue is resolved only for the "postgis3" port, that's OK for me (and
 thanks in advance, it's much appreciated if it can be done).
