That is the precise purpose of the `setup_requires` kwarg. `setup_requires` isn't exactly "neat", though. Among other problems, if your package is installed via pip, installation of `setup_requires` dependencies will ignore installation options passed to pip, so for instance if someone were trying to install your package via an alternative index or local sdists, setuptools would still go out to PyPI for the `setup_requires` dependencies.) I would take a step back and think really hard about how badly your setup.py really needs docutils, and whether you can avoid doing this at all. There isn't any good way to do it that I know of. You could try the alternative-setup-requires that Daniel described and linked to earlier in this thread. Carl
