These features have been implemented only in the 'incminimark' and the 'boehm' GC. For experimentation with other GCs, you can disable these components---like the 'cpyext' module of PyPy---by following the instructions in the bold red text. Note also that if you want to play with the GC, it makes little sense to translate a complete PyPy every time. You should at least have a small RPython program, much simpler than the whole PyPy, and use that for testing. But ideally you should look at the way we write various tests in rpython/memory/.
