All four of my Zope 3.4 KGS buildbot jobs failed with this opaque error last night: Develop: '/var/lib/buildbot/slaves/zope-kgs/py2.5-32bit-linux/build/.' Getting distribution for 'zope.testing>=3.6.0'. error: Permission denied <built-in function listdir> /tmp/easy_install-lHWuqf/zope.testing-3.9.0 An error occured when trying to install zope.testing 3.9.0. Look above this message for any errors that were output by easy_install. While: Installing. Getting section test. Initializing section test. Installing recipe zc.recipe.testrunner. Getting distribution for 'zope.testing>=3.6.0'. Error: Couldn't install: zope.testing 3.9.0 It looks like the tarball uploaded to PyPI has incorrect and extremely restrictive file permissions (000, i.e. none at all). I could upload a fixed tarball to PyPI (if I could make up my mind if it should be 3.9.0 or 3.9.1), but I'm interested in the root cause: how was the tarball generated?
