In that case, the .egg file should go on sys.path immediately before the directory where it is stored. This ensures that a setuptools .egg file will always be discovered before a distutils-installed package/module in the same directory, but it will not override packages/modules that occur earlier in sys.path.
What of distributions installed via setuptools that are *not* installed as eggs?
I don't know. Can you tell me more about that? I'm not particularly familiar with setuptools -- I'm just offering to write the patch because I don't see it getting fixed any other way. Every thing that I have ever installed with setuptools has landed in a file or directory named like "*.egg". For example: site-packages/nose-0.10.4-py2.5.egg site-packages/Sphinx-0.5.1-py2.5.egg site-packages/Jinja-1.2-py2.5-macosx-10.3-i386.egg The installation creates a file "easy-install.pth" that looks like this: % cat easy-install.pth import sys; sys.__plen = len(sys.path) ./setuptools-0.6c9-py2.5.egg ./nose-0.10.4-py2.5.egg ./Sphinx-0.5.1-py2.5.egg ./Jinja-1.2-py2.5-macosx-10.3-i386.egg ./Pygments-1.0-py2.5.egg ./docutils-0.4-py2.5.egg import sys; new=sys.path[sys.__plen:]; del sys.path[sys.__plen:]; p=getattr(sys,'__egginsert',0); sys.path[p:p]=new; sys.__egginsert = p+len(new) % So, where I said ".egg files", you can substitute the name of the things on line 2 through N-1 in the easy-install.pth file. That last line of easy-install.pth guarantees that the .egg files (in this example, they are all eggs) will be placed in the wrong place on sys.path, and that is all I am proposing to fix. If there is another case that does not involve the easy-install.pth file, that is outside the scope of my patch. So, about distributions that are not installed as eggs: Can you tell me a little about it? Can you give me an example of how I can see it happen? Or does it turn out to be irrelevant to my patch?
