yes but building edp takes care of that for you. was that error after install finished and the machine rebooted? edp is a straight forward thing you should not be having so many issue unless theres corrupted media somewhere... like memory, hdd, thumbdrive, dvdrom or dirty disc basically a bad image being generated?
by the way bin/rebuild.sh: line 22: /Volumes/Mac: No such file or directory means that edp is not installed on volume/mac is volume mac your HDD? maybe there lies your issue... just install edp to Mac if thats where osx is and build again for your machine
