There are a number of places in the ports tree where the string "clang<version" is called out. When doing the work to identify stale versions of clang tree-wide, these instances cause extra work.
This tracking PR will list the individual patches to refactor these usages into LLVM_VER, as they are become available after testing on my system.
Note: this refactoring causes portlint to complain but IMHO this complication is worth tolerating to help ease maintainability.
Now see PR 241071.
