Much of this article should be taken with many, many large grains of salt. I've never run into a package that I needed to install which both A) had mandatory dependencies and B) refused to specify them in a way automated tools would understand and resolve. I'm sure there are packages out there which have this problem, because a dependency list is not mandatory in setup.py, but I've not had the experience of encountering such a package and I've been using Python for a living for over a decade now.
