However, one major problem is that to modify the function of the setup.py "build" and "develop" commands one needs to do this in the setup.py:

from setuptools import setup, find_packages from van.potomo import develop, build

setup( name = "HelloWorld", cmdclass = {'build': build, 'develop': develop}, setup_requires = ["van.potomo"], version = "0.1", packages = find_packages(), )

Meaning that you have to manually install van.potomo before tools like buildout can run the setup.py to figure out the dependencies. Is there any way to make that more automatic, especially so that buildout can have a chance?

From my experience with Debian, there's a "Build Dependencies" field in the control file where one can specify such things. I'm kindof hoping there's a setuptools equivalent?

You can use aliases to do this, sort of. In your setup.cfg, do something like: [aliases] build = vp_build develop = vp_develop And then register these commands in the van.potomo package's entry points (i.e., as vp_build and vp_develop). Unfortunately, this only works for *command-line commands* - it's not a general replacement for the commands, the way cmdclass is. Probably a better solution would be to add the ability in setuptools to specify a *string* in cmdclass, instead of a class, so that this approach could work generally, instead of only on the command line.
