I like brew, but it's complete ignorance of OSX deployment target version (macosx-version-min) means it's useless for building software intended to run on machines other than the developer's. Most commercial software in other words. I realise that's outside of it's intended feature set, and it's fine for getting dependencies for other people's github projects or whatever. But what I'd really like is the ability to get dependencies that I can feed into my CI system to build software I intend to give to end users.
