Comment (by snowflake):

 My Mountain Lion system runs in a VM and has a mere 269 ports.

 On El Capitan, Catalina and Big Sur, each have at least 2000 ports.

 I suspect that the build bots will work because they start from a clean
 system and only pull in what they need.  On my big systems the configure
 phase is probably finding something I don't even know exists and this is
 somehow causing a conflict during the build. There could be a duplicate
 macro definition. I have now idea how to find this apart from deactivating
 all ports then activating them one by one until the build fails.

 A better alternative is for me to wait until the buildbots have done their
 builts then install from the archive.
