Hi, I've found that for easy_install fails to install zc.recipe.testrunner for python 2.3 on OS X. % easy_install-2.3 zc.recipe.testrunner Searching for zc.recipe.testrunner Reading http://cheeseshop.python.org/pypi/zc.recipe.testrunner/ Reading http://svn.zope.org/zc.buildout Reading http://cheeseshop.python.org/pypi/zc.recipe.testrunner/1.0.0b6 Best match: zc.recipe.testrunner 1.0.0b6 Downloading http://cheeseshop.python.org/packages/source/z/zc.recipe.testrunner/zc.recip...

Here is a demonstration of that:

import os import tempfile tmp_dir = tempfile.mkdtemp(prefix="easy_install-") example_dir = os.path.join(tmp_dir, 'example') os.mkdir(example_dir) os.chmod(example_dir, 02755) Traceback (most recent call last): File "<stdin>", line 1, in ? OSError: [Errno 1] Operation not permitted: '/tmp/easy_install-UlgpCH/example'

I see the same failing behaviour for handling of tempfile and chmod for Python 2.4 on OS X. However there is an explicit egg for python 2.4: http://cheeseshop.python.org/pypi/zc.recipe.testrunner/1.0.0b6#download which does not have set-group-ID-on-execution bit set for any of the archive members. So the egg easy installs just fine in that case. And I don't see any such problems using FreeBSD. Michael
