    The command has been installed with the prefix "g".
    If you do not want the prefix, install using the "with-default-names" option.

    If you need to use these commands with their normal names, you
    can add a "gnubin" directory to your PATH from your bashrc like:

        PATH="#{opt_libexec}/gnubin:$PATH"

    Additionally, you can access their man pages with normal names if you add
    the "gnuman" directory to your MANPATH from your bashrc as well:

        MANPATH="#{opt_libexec}/gnuman:$MANPATH"
