Build on macOS 14.5 is broken

[AaronFeickert]

The build instructions on macOS 14.5 do not work.

Since python-setuptools is not installed by the instructions, it must be added separately: brew install python-setuptools

There is also an issue with m4 without an obvious solution. Running xcode-select --install is not necessary, as the operating system reports the tools are already installed. The build process reports that m4 is not installed, but triggers a GUI popup asking to install it. After doing so, the same issue arises, and will trigger the same installation popup.

Running which m4 gives: /usr/bin/m4

Running xcode-select -p gives: /Library/Developer/CommandLineTools

Following this path, /Library/Developer/CommandLineTools/usr/bin/gm4 --version shows GNU M4 1.4.6 as the version.
