Comment (by PifPof73):

 hey - it would be very helpfull if you could leave a link to the PR in
 github or to the qt5-qtbase 5.15.1.
 I am not very firm in manipulating macport sources but I need the qt5
 framework running asap and just got stuck after the update on big sur.
 So if you have a workaround, please think of the noobs and please type
 your remarks with some chance to reproduce it without re-inventing your
 complete findouts.

 So - where can I find the PR and how do I put it inside my macPorts
 Sources to rebuild the now missing frameworks?

 BTW, I do have the same issue with port <qt4-mac>.
 Thx.
