I'm happily using swank-clojure, installed via elpa. But I'd like to do some work with deftype, defprotocol, etc., which aren't aren't available in clojure 1.1.

To use my own class paths, I'm using the excellent suggestion by Rick Moynihan in the stackoverflow question about setting custom classpaths, which was to set up a script like:

#!/bin/bash 

java -server -cp "./lib/*":./src clojure.main -e "(do (require 'swank.swank) (swank.swank/start-repl))"

And that works swimmingly if the clojure jar file in lib is 1.1, but with 1.2, it blows up:

Exception in thread "main" java.lang.NoSuchMethodError: clojure.lang.RestFn.<init>(I)V (macroexpand.clj:1)
    at clojure.lang.Compiler.eval(Compiler.java:5274)
    at clojure.lang.Compiler.load(Compiler.java:5663)
    at clojure.lang.RT.loadResourceScript(RT.java:330)
    at clojure.lang.RT.loadResourceScript(RT.java:321)
    at clojure.lang.RT.load(RT.java:399)
    at clojure.lang.RT.load(RT.java:371)
    at clojure.core$load__5663$fn__5671.invoke(core.clj:4255)
    at clojure.core$load__5663.doInvoke(core.clj:4254)
    at clojure.lang.RestFn.invoke(RestFn.java:409)
...and many, many more

So is there some magical incantation to make this work, or is clojure 1.2 compatibility not there yet?
