[python-crypto] porting of m2crypto on python 3

Hi,
I have tried to give another shot to
https://bugzilla.osafoundation.org/show_bug.cgi?id=12853 ("Python 3.*
support" for m2crypto). My current repo is
http://luther.ceplovi.cz/git/m2crypto.git/ (branch "python3").
Build runs without errors (but with tons of warnings; see below the log
of python3 setup.py build), but when I try to import created build I get
undefined symbol:
matej at wycliff: M2Crypto (python3 %)$ python3
Python 3.3.0 (default, Oct 2 2012, 09:27:11)
[GCC 4.7.2 20120921 (Red Hat 4.7.2-2)] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> import __m2crypto
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
ImportError: ./__m2crypto.cpython-33m.so: undefined symbol: PyFile_Check
>>>
That's probably problem with SWIG, isn't (I don't have PyFile_Check
anywhere in my source files)? Does anybody have any idea how to work
around it?
Best,
Matěj
