Those instructions haven't worked on macOS since at least autumn 2019.

See: <https://bugs.llvm.org/show_bug.cgi?id=45880>

I'm just a clang user, not a developer, but I find it rather baffling that 'getting started' instructions don't work for 1.5 years.

It would be less bad if there were binaries for macOS, but there's still none for clang 11.0.1, released over 2 months ago:


nor have there have any binaries for any of the clang 12 release candidates.

So you can't build it yourself, and you can't download an executable.  Rather sad. :(
