Hi daniel..I've followed your tutorial and download this project..I run lein deps and this download all dependencies, but when I type cljsbuild once I get:

Hi cocodrino, Thanks for you interest in my post

I made a bit of an error in the blog concerning the fact that you need to check out a different branch for this project

git clone https://djhworld@github.com/djhworld/testproject.git
git checkout twitter-post2

However that aside, a similar issue was raised for the project on my previous post ( scroll down a bit)

The common factor between your issue and his is you're both on Windows which might be causing the problem.

I'm on a Windows machine at the moment (at work) and I've run the clojurescript compiler OK and run lein run without any issues - however I am doing this via Cygwin.

Could you try using cygwin or a *nix based box?
