The OS I'm using is Mac Monterey and I've installed llvm thru Homebrew and exported the path by

export PATH="$(brew --prefix llvm)/bin:${PATH}"

but it still references the version already installed in /usr/bin/llvm. In fact, it gives me the following

llvm-ar failed: error executing command /usr/bin/llvm-ar @bazel-out/host/bin/external/m4_v1.4.18/libm4_lib.a-2.params

How can I get it to reference the one installed thru brew on /usr/local/opt/llvm?

MacOS ships with llvm which does not contain llvm-ar, so you will need to add it to your PATH and also export clang variables
