Today I was unable to build zodbbrowser using its bleeding-edge.cfg which unpins all package versions. It was unable to install ZODB3. I can reproduce the same error with pip: $ virtualenv test $ test/bin/pip install ZODB3 Downloading/unpacking ZODB3 Downloading ZODB3-3.10.5.win32.zip (1.8Mb): 1.8Mb downloaded Running setup.py egg_info for package ZODB3 Traceback (most recent call last): File "<string>", line 14, in <module> IOError: [Errno 2] No such file or directory: '/tmp/test/build/ZODB3/setup.py' It looks like {zc.buildout,easy_install,pip,setuptools,distribute} see the ZODB3-3.10.5.win32.zip as a simple .zip source tarball of ZODB3 version "3.10.5.win32". http://pypi.python.org/pypi/ZODB3/3.10.5 contains various proper win32 eggs in addition to that .win32.zip. The PyPI page for 3.10.4 did not have any weird .win32.zip files. Can someone please remove that "dumb" binary file which is "built for Windows XP" (and doesn't even mention for which Python version)?
