sorry, this is not really a maintained project anymore - you're seeing an error from newer clojure and older ring version that has a spec violation

[andeemarks]

Hi @SSYH - if you are still having this problem, try changing the lein-gorilla plugin you are using...

:plugins [[org.clojars.benfb/lein-gorilla "0.7.0"]]

I was having the same problem as you, but found a more current fork of the original lein-gorilla plugin which fixed these errors.
