I hate to down-rate the entire project because of the installer, but ... why in the heck do you need to install XQuartz if you've got the latest version of OS X? From the XQuartz site: "Together with supporting libraries and applications, it forms the X11.app that Apple has shipped with OS X since version 10.5." I have 10.9.4, so it's already installed. Why doesn't the program find it?
excellent tool on linux and (if you have to) windows
