Fair warning: getting to the reasoning point of this process requires an extraordinary amount of hand waving. We're about to go down the rabbit hole.
Fortunately there is a tool called Leiningen that makes working with Clojure extra easy. I did the following steps on my CSL account - commandline stuff is always easiest on unix.
Grab the lein
script. Easiest way to do that is just wget
wget https://raw.github.com/technomancy/leiningen/stable/bin/lein --no-check-certificate
This will grab the lein program from github. You will need to put it somewhere in your path. On the CSL servers I have ~/bin in my path so I dropped it there.
