It's worth mentioning that getting Servo to build and run on OS X is very straight forward and worked for me the first time.

Here is the github repo: https://github.com/servo/servo

You should also try https://github.com/glennw/servo-shell (it's a webpage, and you don't need to rebuild servo or anything though building it in release mode is preferred), which gives you a browser experience.
