Comment (by thetrial):

 I have to add three things, respecting this and maybe even #62693:

 * Due to the problems I had only on one machine, and them not appearing on
 the other – I decided to »transplant« /opt from one to the other. Applying
 root/wheel 755 was a bit tricky, but I did it with batchmod. Afterwards I
 made a port clean --all all. At the moment everything runs fine except
 keepassxc, that seems abandoned, #62220.
 * While doing that I noticed that there is a specialty that might (?) play
 a role: I use ccache. I applied a ccache -C and deleted all subfolders in
 its directory.
 * Last but not least, I think this is the right place and time to mention
 a very big thank you for you all, who you are so engaged in macports! :-)
