I'm following the "Getting started" guide but when I get to running `lein ring server` for the first time I get the following crash:

I'm new at Clojure so not quite sure what to do from here. I am running the latest version of Leiningen.

`some->` is available in clojure only since 1.5. As it turns out, liberator specifies a default dependency on 1.4 which makes the example fail. This is a bug which needs to be fixed. As a workaround change the clojure dependency in your project (or liberator) to 1.6.0 (or later :)
