Now I try to find in which package the content of /usr/lib/clang might reside in one of
the pkg-base tarballs one could find here:

https://alpha.pkgbase.live/current/FreeBSD:14:amd64/latest/

to extract the part missing in the hope I can fire up buildworld again.
I tried the usual suspects like those packages with "lib" or "compiler" in the name,
without success :-(
