 Great, thanks!

 > and add {{{clang}}} in there wherever you want to.

 Could you please explain? That line already has a whole bunch of
 {{{macports-clang-xx}}}...? Or do you mean plain {{{clang}}} entry to mean
 the the Xcode clang (whatever version the current installed Xcode happens
 to be)?

 > a (nearly) full list of the compiler options is here:
 ​https://trac.macports.org/wiki/UsingTheRightCompiler

 Yeah, I checked that URL - it doesn't even have {{{macports-clang-13}}}...


 > If you have done something non-standard on your system out of a personal
 choice, that makes it different than the buildbots, and then you get a
 build error that the buildbot does not get, IMHO it is not fair to open
 tickets for situations like that

 Yeah, I get your point. Though, if, e.g., something fails to build with
 {{{macports-clang-13}}} - wouldn't you want to know...?
