I installed clojure and clojure contrib manually, through homebrew and mac ports all of them gives me this error. I can get other parts to work. What gives?
edit this question seems similar Can not get clojure-contrib to load - FileNotFoundException However i can load some parts, and i install through ports/brew so the versions should be in sync
It's better to use clojure & clojure-contrib not directly, but through some project, for example, managed by leiningen - it will fetch correct versions of clojure & clojure-contrib, plus some other dependencies that you're specify. You can also look onto my Lein introduction article on this topic
