At this point it works fine with the following project.clj (notice the 'slingshot' dependency):

(defproject toopzi "0.1.0-SNAPSHOT"
  :description "FIXME: write description"
  :url "http://example.com/FIXME"
  :license {:name "Eclipse Public License"
            :url "http://www.eclipse.org/legal/epl-v10.html"}
  :dependencies [[org.clojure/clojure "1.4.0"]
                 [slingshot "0.8.0"]
                 ])
But as soon as I add:

(defproject toopzi "0.1.0-SNAPSHOT"
  :description "FIXME: write description"
  :url "http://example.com/FIXME"
  :license {:name "Eclipse Public License"
            :url "http://www.eclipse.org/legal/epl-v10.html"}
  :dependencies [[org.clojure/clojure "1.4.0"]
                 [slingshot "0.8.0"]
                 [myjar "1.0.6"]
                 ])

I get:
