That directory is in the default sys.path for both the Apple-supplied Python 2.7 in Lion and for the python.org Python 2.7's but that doesn't mean both versions use the same site-packages directory: $ /usr/bin/python2.7 -c "import distutils.sysconfig; \ print(distutils.sysconfig.get_python_lib())" /Library/Python/2.7/site-packages $ /usr/local/bin/python2.7 -c "import distutils.sysconfig; \ print(distutils.sysconfig.get_python_lib())" /Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-pack ages That means that, by default, packages installed by Distutils-based installs (setup.py, easy_install, pip, et al) will be installed to the corresponding directory for each version. The python.org OS X Pythons (and built-from-source framework builds) add the Apple-specific directory to the search path in order to allow sharing of installed third-party packages between the two. The feature was added in 2.7 and 3.1+ and tracked in Issue4865 (http://bugs.python.org/issue4865). Please open a new issue on the tracker if you have examples of how this is causing problems.
