Clojure 1.2 compatibility

[the-kenny]

Hello,

I used your library a bit in the past and wanted to use it again in a small personal project. Here are my changes for Clojure 1.2 compatibility (I mentioned 1.2.1 in the commits - my fault)

However, I couldn't get it to run. I'm stuck with an exception I don't really understand. Here is the sldb-output: https://gist.github.com/668889 I'm sure it isn't really hard to fix it when you understand the code ;-)

I hope I could help you with bringing this cool library up-to-date.
