This script requires the user #{ENV['USER']} to be an Administrator. If this | |
sucks for you then you can install Homebrew in your home directory or however | |
you please; please refer to our homepage. If you still want to use this script | |
set your user to be an Administrator in System Preferences or `su' to a | |
non-root user with Administrator privileges. | |

It appears Homebrew is already installed. If your intent is to reinstall you | |
should do the following before running this installer again: | |

not intentional, please restore the default permissions and try running the | |
installer again: | |
