Clojurians Log v2

Hi all, n00bie here trying to get Reveal to work with leiningen. Using v1.3.277 (which looks to be the latest) in my profiles.clj, I get this error:

➜  ~ lein repl

However, after a lot of scouring in the channel, I saw that people tried out v1.3.265, and that one seemed to work.
