Comment (by mouse07410):

 > clang-13 was not chosen as the default clang compiler because it is too
 new, and is likely to cause too many builds to fail

 OK, understood. I might disagree - but I get your point.

 > You can manipulate this however you want on your own system by monkeying
 around with your {{{default_compilers}}} setting in {{{macports.conf}}}

 Would you mind please give some references/pointers? The installed
 {{{/opt/local/etc/macports/macports.conf}}} does not contain
 {{{default_compilers}}} setting, nor is it mentioned in
 [https://guide.macports.org/chunked/internals.configuration-files.html].

 I'd like to at lease see how to do it, and what are the
 capabilities/options/choices if I go that route.

 > Just don't open any tickets if you do that :>

 Now that **is** harsh! ;-)

 > as mentioned by Josh, what you have installed already cannot be used as
 a criteria for the compiler that is chosen. I know it seems perhaps
 logical, and in the past I have tried that idea, but it doesn't work out
 in the broad mix of 100,000 builds and so it is not going to be supported
 as a plan.

 Indeed, what I suggested did sound logical to me - but I have no
 experience actually maintaining Macports for many users, so can't argue
 with your point.
