defprotocol is a Clojure version 1.2 thing. i.e. it does not exist in any released version of Clojure yet. It looks like you're trying to use a version of clojure.contrib that is too new for your version of clojure. I've not used clojure.contrib.json, but the version in clojure-contrib 1.1.0 should work with clojure 1.1.0. > I tried clojure-contrib 1.1.0 with clojure 1.0.0 and 1.1.0.
