I don't quite see your point here. That most of the programmers can't create Yum or APT repository? Or can't setup VCS server?

Most programmers are more interested in jumping into every new sexy library that just happened to appear than to make their working environment reproducible, robust, and controllable. That's why they don't think of how to package their code for installation and deployment, don't think where and how to keep their dependencies (not thinking about dependencies causes explosion of dependency fractal, which is a collateral damage), don't think how to work off-line, and so on.
