You're probably using Clojure 1.7.0 alpha 2, which introduced a new function called "cat" into the core namespace, which overlaps with a function in instaparse.
A couple nights ago, I updated instaparse to version 1.3.4, with an update to deal with this change in alpha 2, but pigpen has not yet been updated to use that version of instaparse. You can either go back to a non-alpha release of Clojure, or wait for the pigpen folks to update, or perhaps there is some leiningen-fu you can do in the project.clj file to override the instaparse dependency loaded by pigpen with instaparse 1.3.4.
