Okay, so you did need that also (I thought somehow it would have been
taken care of by pygtk). I got something slightly cleaner (and more
complete) from somewhere else though:

#if PY_VERSION_HEX < 0x02050000 && !defined(PY_SSIZE_T_MIN)
typedef int Py_ssize_t;
#define PY_SSIZE_T_MAX INT_MAX
#define PY_SSIZE_T_MIN INT_MIN
typedef inquiry lenfunc;
typedef intargfunc ssizeargfunc;
typedef intobjargproc ssizeobjargproc;
typedef intintargfunc ssizessizeargfunc;
typedef intintobjargproc ssizessizeobjargproc;
typedef getreadbufferproc readbufferproc;
typedef getwritebufferproc writebufferproc;
typedef getsegcountproc segcountproc;
typedef getcharbufferproc charbufferproc;
#endif

But I don't know where this really belongs... I guess at the top of
gv.override is fine, unless someone else has a better idea.

I never encountered this error... and I must admit I am not familiar
enough with distutils to be able to diagnostic. Help anyone?

You mean hugin the panorama stitching software? I used it last year
for a personal project. Nice work on this!
