If you do not want the prefix, install using the '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_prefix}/libexec/gnubin:$PATH" Additionally, you can access their man pages with normal names if you add the "gnuman" directory to your MANPATH from your bashrc as well: MANPATH="#{opt_prefix}/libexec/gnuman:$MANPATH" EOS end end
