Not saying it isn't an approach, I'm just saying,it's apples and oranges. When someone suggests that OSX doesn't have a linux style package management, they are technically correct.
What does "linux style" even mean? Linux is a kernel, it doesn't define how a package manager is supposed to work. Gentoo has been source compiling from ages, and is a linux distribution. If you're looking for technical correctness, your initial comment[1] is wrong in the context of Portage.
If you're looking for a reason to dislike a project like homebrew, bring up that it's nowhere close to complete system management. There's huge parts of OS X that I have to have already installed through other means just to get it up and running, and plenty more that I simply cannot install through it. That's a lot more important than wether or not you have to wait for package compilation.
