Juce Demo Plugin on lion osx

Hello All,
I tried to compile the juice demo plugin under lion with Xcode 4.2.
I saw that the project contains the old AUDispach and AUDebugDispatcher.
Are the AU wrapper files updated for lion ?
Thanks in advance!

If you delete them, you will be fine.

enlighten me a bit moreā€¦
what do you mean by delete them?
i have tried to replace files, calls etc nothing worked
your help is much appreciated
