How to use PIL with PyPy?

I searched a little bit but I couldn't find a tuto to use PIL with PyPy. According to PyPy's blog, PIL is supported.

I installed PIL with pip in my PYTHONPATH.
After the download, pip make 2 .pyd files: _imaging.pyd and _imagingmath.pyd.
After the install, I copied %PYTHONPATH%/lib/site-packages/PIL to my PyPy site-packages directory.
When I run my script (which uses PIL), it says it can't import the _imaging C module.

How should I do it ?

edit: I run this on Windows 7 x64 (python 2.7.1 32bits)

here is the traceback (pypy 1.4.1 windows binary):

Traceback (most recent call last):
  File "app_main.py", line 53, in run_toplevel

ImportError: The _imaging C module is not installed

Solution

I did this:

$ /opt/pypy-1.4.1/bin/virtualenv test
$ cd test
$ bin/pip install PIL
...

Worked like a charm. So do that. :)
