 What about Big Sur build-bots? If they successfully create clang-12
 binaries - why am I unable to just download pre-built (which would be my
 preference)?

 Would you be able to at least try what they suggested and see if it does
 not make things ''worse''?

 fix.


 Understood. My goal is to make this fixed, somehow. If the upstream
 maintainers are at least willing to consider ''some'' fix, it would be
 great if the Macports team could validate it.
