getting the error "the package com.briansteen does not exist, you may have a library missing." which i gather is something to do with sunflow or hemesh to sunflow.

followed the steps to the tee for running  hemeshGUI lite (which worked nicely) and then hemeshGUI(which didnt)
(from here: http://www.creativeapplications.net/processing/hemesh-and-hemeshgui-processing/)

Im a total processing noob so any pointers on how to get past this would be massively appreciated.

Welcome all by the way!
