"No module named pygame.base" - pygame and pypy

After several attempts and errors, I was able to install pygame 1.9.2a0 in pypy3, downloading the current version via mercurial and installing via / path / pypy3 setup.py

But at the moment of giving import, I get the following error:

Traceback (most recent call last):
  File "/home/rafael/PycharmProjects/pygame-teste/__init__.py", line 3, in <module>
    import pygame
  File "/opt/pypy3-2.4.0-linux64/site-packages/pygame/__init__.py", line 133, in <module>
    from pygame.base import *
ImportError: No module named pygame.base

This error also happened frequently before in python3, (when I used Debian Wheezy), but it worked fine in PyCharm. Now that I'm using Jessie and pygame works perfectly in python3, this error appears pro pypy (and neither does Pycharm work)

Any ideas?
