 I do not know . Self i just started with mac ports 2 months ago. I’ve been
 out for a while. But before I used to work with linux . Actually I started
 so wath 20 years ago with debian and then changed to ubuntu. But the
 problems are there since longer I think and not since clang 16 . Oneof the
 causes is that a lot of packages are build and just needed to be
 downloaded. They were already build most probably before the clang was
 upgraded to versions above 14 . But then yes a new version somewhere
 needed upgrade for some libs and so and we must build locally with the
 result we see now. And typical to this is that just a function is only
 sometimes used and only with some packages . On top of it with error
 messages who are misleading . I start the more thinking that the real
 problem is there since clang 15 due to a function wichbis not compatible
 anymore with older macos guess all os below 10.14
