Tripwire install on macOS

This is a bare-bones tutorial for installing Tripwire on the macOS. It is assumed that the person using this tutorial knows UNIX, the bash shell, how to unzip files and how to compile software. It is also assumed XCode is already installed and that you are the administrator with sudo privileges. If you don’t understand the preceding words, DON’T ATTEMPT THIS! STOP HERE!
