 Replying to [comment:6 reneeotten]:
 > I have done the update to 6.8.0 and am currently building the last
 subports to make sure that everything works. But at least the
 {{{qt6-qtwebengine}}} port builds successfully now, that was the final
 issue I had when attempting to update to 6.7.3.

 sometime this weekend.

 On buildbots pretty much everything broken now: #71431
 So no prebuilt ports.

 Build on Catalina fails in the very beginning.
 Build on Sonoma takes hours with yet unknown result, but on buildbots it
 failed.

 Wonder how Qt folks release something completely defunct.
