    To use this build of Zsh as your login shell, add it to /etc/shells.

    If you have administrator privileges, you must fix an Apple miss
    configuration in Mac OS X 10.7 Lion by renaming /etc/zshenv to
    /etc/zprofile, or Zsh will have the wrong PATH when executed
    non-interactively by scripts.

    Alternatively, install Zsh with /etc disabled:

      brew install --disable-etcdir zsh
    EOS
  end
