I've gotten the ztk kgs tests to pass with Python 2.5 on Mac OS X. I've got them mostly passing with on Python 2.6. The only failure I'm getting is for zope.testing and it's due to a Python 2.6 hotshot bug: http://bugs.python.org/issue6710 I'm not sure what to do about this. Perhaps I should disable this test, or maybe even the feature for Python 2.6. When building, I'm getting some deprecation warnings: /Users/jim/.buildout/eggs/infrae.subversion-1.4.5-py2.6.egg/infrae/subversion/Common.py:4: DeprecationWarning: the sets module is deprecated from sets import Set # For python 2.3 compatibility /Users/jim/.buildout/eggs/z3c.recipe.compattest-0.7-py2.6.egg/z3c/recipe/compattest/recipe.py:4: DeprecationWarning: The popen2 module is deprecated. Use the subprocess module. import popen2 It would be great if someone would fix these. :) When running the tests, the only deprecation warnings are from twisted, which we can't do anything about. BTW, if you want to try this yourself, use the buildout at: svn://svn.zope.org/repos/main/zopetoolkit/branches/jim-kgs/kgs Jim -- Jim Fulton
