Hi! I should really add this to the docs page, but engulf's JAR is compiled for JDK7 (though I could likely build a JDK6 compatible one, haven't had time to check).

I'll add a note about this to the site, but in the meantime I recommend downloading JDK7 from http://www.oracle.com/technetwork/java/javase/downloads/index.html

After you install it, verify that Java7 is the default by opening Java Preferences.app (you can find it in spotlight). Or, try running java -version in a terminal to verify that you are running Java 7. Let me know if that helps!
