What distro are you using that doesn't have a proper package manager? Brew exists precisely because this has been standard for years/decades on linux but OSX hasn't had anything built in.
Of course they all do - the desire for good homebrew support (linuxbrew already exists) comes from the ease of writing formulas and scripting in Ruby, it's infinitely easier than packaging for apt / apk. Plus the fact that 80% of developers use Mac, but you can't leave the 20% out in the rain. This is for in-house software, not third party.
