      # https://github.com/actions/runner-images/issues/9471. The issues comes
      # and goes depending on runner image versions. I believe I originally
      # found the workaround step below somewhere in:
      #   https://github.com/actions/setup-python/issues/577
      # We have the problem because libpng has python as a dep.
      # * Scenario 1: libpng forces brew to install python in `/usr/local/bin`.
      #   Then we need to clear out the pre-provided symlinks or brew will fail.
      #   Further steps use newly installed python.
      # * Scenario 2: libpng is up-to-date in the current runner. For this case,
      #   clearing out the links is safe because the runner's default path
      #   should still include
      #   `/Library/Frameworks/Python.framework/Versions/Current/bin/python`
      #   (with a lower priority than `/usr/local/bin`) and pre-installed
      #   python remains available.
      # * For both scenarios, we should install pyyaml via pip, not brew, so
      #   that it is installed for the correct python version. Installing it
      #   via `brew` doesn't work right in scenario 2.
