Comment (by kencu):

 Homebrew found a list of about 20 formula where this issue was causing
 issues.

 In the end, they moved {{{libc++.1.dylib}}} out of the directory where all
 the other LLVM/clang libs are stored, and into a subdirectory, so it would
 not be automatically found during the link phase if
 {{{-L/opt/local/libexec/llvm-14/lib}}} was being used to find the LLVM
 libs, and therefore cause errors.
