Second recommendation for MacPorts

It predates Homebrew by a bit and is under Apple's http://www.macosforge.org umbrella of OSS projects, so as close to 1st party support as you can get.

MacPorts rocks. No ports breaking when upgrading MacOS as can (or could,not sure if that's still an issue) with Brew.

Third one for macports. It's more sane, at least for multi users support (I create an user for each contract work)

It seems like Apple also closely work with Homebrew - https://news.ycombinator.com/item?id=41708046#41711168
