Can I ask what you use your package manager for? My experience on the Mac is that it's mostly used by developers that want to install a package and don't want to have to manually install the 30 other dependencies by hand. For that use case, installing the dependencies along side the module that you actually wanted seems like an eminently reasonable thing to do, and certainly in my case it's pretty much exactly what I want from a package manager on the Mac. I assume if it bugs you that you have a different use case from mine. I would be interested to hear what it is (have I been missing opportunities on my Mac all this time???)
