Clojurians Log v2

Hello. Having some fun playing with overtone today. Trying to fine where the ugen "out" is defined. Tried greping and using (meta #'overtone.core/out)... got: :orig-ns http://overtone.sc.ugens... which is not correct. Would like to build my own jar to add some logging to the immigrating bit but the "clj prep; line install" on the readme doesn't work... probably because the project.clj was removed... any help on any of that? thanks in advance!
