qtmacextras examples does not work + lack of documentation and examples

As it says in the headline: None of the examples compiles. No examples for dealing with native widgets or unified toolbar. At the very least, the latter is important for a professional looking Mac application. I've been waiting for qtmacextras to become available since 5.0 beta... 4.8 is a no-go because of certain widget problems on Mac. I have a hard time figuring out how 5.2 beta testing is supposed to happen when neither docs or working examples are available.

Does this mean that we have to wait for full qtmacextras functionality until 5.3? If yes, something is definitely wrong with the priorities. I don't want to sound like a brat here, because I really respect the work being done - but if the vision of Qt being a serious competitor to native development is going to be fulfilled, all platforms need the same amount of love.
