And now for something completely different: ``in pypy you are always at the

wrong level, in one way or the other''

>>>> import pygtk

>>>> dir(pygtk)

>>>> pygtk._get_available_versions()

{'2.0': '/home/ethan/pypy-2.0-beta1/site-packages/gtk-2.0'}

so far, nothing to bad, but..., now starting bad dream on here.  ImportError: No module named glib._glib

>>>> import gtk

Confirm my installed list whether have libglib2.0-dev, so here might something to missing...

ethan@ethan-GA-880GM-UD2H:~$ dpkg --get-selections | grep glib

gir1.2-glib-2.0                                 install

...

libglib2.0-0                                    install

libglib2.0-data                                 install

libglib2.0-dev                                  install

After checked the _glib.so is in python2.7/dst-packages/glib/; copy or link in the file in pypy/site-packages/glib/

ethan@ethan-GA-880GM-UD2H:~$ ls /usr/lib/python2.7/dist-packages/glib/

So, that's mean pypy need to define _PyObject_CallFunction_SizeT, and I find Python include *.h files, in /usr/include/python2.7/abstract.h file can finding declared as below, line 8 and line 326:



#ifdef PY_SSIZE_T_CLEAN
#define PyObject_CallFunction _PyObject_CallFunction_SizeT
#define PyObject_CallMethod _PyObject_CallMethod_SizeT
#endif

...

PyAPI_FUNC(PyObject *) _PyObject_CallFunction_SizeT(PyObject *callable,

                                                         char *format, ...);
