Hi, I've started using setuptools as a developer quite recently, and appreciate the extra features. I've a question though, regarding the way dependencies are resolved when installing such a package: I've written a package that uses elementtree, and would have found natural to add it in install_requires. However, I've already installed it as a debian package, and in the current state setuptools tries to reinstall over it. So, should I add some extra logic to the setup.py script (ie, try the dependencies myself) or is there a way to tell it "don't update the dependence if you can already import the module" in a convenient way?
