How to use a .so file of a Python version in a different
version\distribution of Python?

I'm working with a Mac trying to use OpenCv in Canopy. I've install OpenCv
Python binding with Macports. And it works fine in my Python 2.7.5, the
Mac default version. When I try to us it in Enthought Canopy Python 2.7.3
| 64-bit |. Python can't find the cv module. I've try to add to the PYTHON
PATH all the path of the first version I mentioned but when I add the path
with site-packages the kernel crash. So I tried to copy the cv.py and
cv2.so in the site-packages (e.g.
'/opt/local/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages')
of Canopy but it crash too. I've tried to create a soft link but it
doesn't work. This is the log:

How can avoid that?Thanks a lot.
