org.flexunit.listeners.UIListener not found, and other problems

I have a basic setup of FlexUnit that comes with the latest FlashBulider. I import a bunch of SWC's in my project and try to follow instructions from here:

http://docs.flexunit.org/index.php?title=Setting_up_a_FlexUnit_4_Proje ct

I got an error saying defintion of UIListener could not be found.

Then I checked the AS docs here: http://docs.flexunit.org/asdocs/index.html

And found out there is no UIListener class at all

So I realized that core.addListener takes IRunListener, and change the code to this:

core.addListener(IRunListener(uiListener));

Sadly, when run. there was a runtime error with this line:

<flexui:TestRunnerBase id="uiListener" width="100%" height="100%" x="0" y="0" />

Saying TestRunnerBase does not implement the IRunListener intarface,
