[Zope] Iimport IPossibleSite not possible

Tue Sep 11 16:16:30 UTC 2012

Thanks everybody for the quick response.
As far as I understand I should do a buildout installation instead of my 
simple path_to_python2.7 setup.py install?

When I try buildout, it fails already with zope.testing :

bin/buildout
Develop: '/opt/Zope2-2.13.15/.'
warning: no previously-included files matching '*.dll' found anywhere in 
distribution
warning: no previously-included files matching '*.pyc' found anywhere in 
distribution
warning: no previously-included files matching '*.pyo' found anywhere in 
distribution
warning: no previously-included files matching '*.so' found anywhere in 
distribution
While:
  Installing.
  Getting section test.
  Initializing section test.
  Installing recipe zc.recipe.testrunner.
Error: There is a version conflict.
We already have: zope.testing 4.1.1
but zc.recipe.testrunner 1.2.1 requires 'zope.testing>=3.6.0,<3.10.0'.

Is there zope.testing >=3.6.0,<3.10.0 to be installed and then step by step 
the next errors to be eliminated or would it be possible to take a shortcut 
and install some older version of python or the site-packages?

Is there a way to avoid buildout at all - for example switching to an older 
python2.6 and then try a simple installation with 2.13.15 again?

Mario
