OS=Ubuntu 9.10
Python version=2.6
After install a zope module using pip, for example z3c.password your zope installation gets broken.

This is because pip have installed the module in /usr/local/lib/python2.6/dist-packages/zope and the original module zope.interface is in /usr/share/pyshared/zope/interface/ and has minor relevance when importing.

Quick fix:
cd /usr/local/lib/python2.6/dist-packages/zope
sudo ln -s /usr/share/pyshared/zope/interface/

As you may know, there are no packages yet for Python2.6 in debian or ubuntu. If you want to install it you can do it by hand and it will work perfectly (it did for me)

Google a bit and you will find this post: http://blog.pythonaro.com/2008/10/horrible-hack-to-get-python-26-on.html

You can follow the steps in the post without problem, then remember to update your supported and default versions under /usr/share/pyhton/debian_defaults

Also you can link modules available in 2.5 to be used by 2.6, for example Ipython, it works perfectly. Do symlinks from python2.6/site_packages/ pointing python2.5/site_packages. Although this is not the correct way, the correct way should be reinstall those modules under your new configuration.

But what about mod_python? it still remains to Python2.5 right? YES

Well, you have to do the same, download it from modpython.org and make and make install, be sure to install apache2-dev it will provide you with a tool needed in the compilation time.

All should work, also django is working perfectly in my new Python & mod_python 2.6 conf. under debian.

cheers!
