Compiling with Closure Compiler's ADVANCED mode

So I've tried today to compile React in advanced mode and the first error I've got was 

```
Uncaught Error: Invariant Violation: EventPluginRegistry: Cannot inject event plugins that do not exist in the plugin ordering, `SimpleEventPlugin`.
```

I guess I should strive to get minimally working (breaking, I mean) example, and I'll try to do that without dropping my whole setup on you, but this requires a bit of time, I'm not sure if it will be hard to reproduce it.
