Do you suffer from requiring different versions of the same library, or have some other kind of non trivial dependencies?

This will mark me out as a Luddite but I am still quite happy with a 5 line setup.py and “pip install .”

  $ cat setup.py
  from setuptools import setup
  setup(
    install_requires=['arrow'],
    packages=['dogclock'],
    scripts=['scripts/dogclock'])
