Hello, I'm wondering if a --no-dependencies option would be useful. In Gentoo we edit every setup.py file that has install_requires, setup_requires, or extra_requires and remove that with sed or a patch because our package manager takes care of installing all dependencies and because users may already have packages installed previously without setuptools (in python 2.4). We've found that can cause problems[1] and are considering using --single-version-externally-managed, but ideally we'd like to use the full features of setuptools (without losing the ability to install multiple versions, require-ing specific versions etc.). Would an option similar to --single-version-externally-managed that simply doesn't check for installed dependencies and does not try to download and install any dependencies be possible?
