During pip install ledfx, the pyaudio dependency failed:

➜  ~ pip install pyaudio
DEPRECATION: Configuring installation scheme with distutils config files is deprecated and will no longer work in the near future. If you are using a Homebrew or Linuxbrew Python, please see discussion at https://github.com/Homebrew/homebrew-core/issues/76621

I was just kind of annoyed and was checking obvious things like python versions; I had just upgraded my Homebrew for the nth time so was expecting things to go south.

I was googling for the wrong search terms at first, not spotting the clang error until later.

I then came across this StackOverflow post:
https://stackoverflow.com/questions/63972113/big-sur-clang-invalid-version-error-due-to-macosx-deployment-target#

I tried the suggested 'switch':
➜  ~ sudo xcode-select --switch /Library/Developer/CommandLineTools

but the clang version didn't change:
➜  ~ clang --version
Apple clang version 11.0.0 (clang-1100.0.33.12)
Target: x86_64-apple-darwin20.5.0
Thread model: posix
InstalledDir: /Library/Developer/CommandLineTools/usr/bin

I then deleted the XCode commandline tools:
➜  ~ sudo rm -rf /Library/Developer/CommandLineTools

And reinstalled it: 
➜  ~ sudo xcode-select --install
xcode-select: note: install requested for command line developer tools

This takes quite a while (to download and install, 20 mins); opens a GUI

Now checking my clang version again:
➜  ~ clang --version
Apple clang version 12.0.5 (clang-1205.0.22.11)
Target: x86_64-apple-darwin20.5.0
Thread model: posix
InstalledDir: /Library/Developer/CommandLineTools/usr/bin

And now the pyaudio and ledfx installs went off without a hitch.
