title: How to run gprolog on macOS Sierra
body: <p>I have just installed gnu-prolog using <code>brew install gnu-prolog</code>. When I try to run <code>gprolog</code> in the terminal I get <code>gprolog: command not found</code>. I tried doing the same to my other machine that is running ElCapitan and all worked perfectly.</p>
  
  <p>Is there a way for me to get <code>gprolog</code>to work for macOS Sierra?</p>
