Homebrew is not really pro in any way: they force updates, deprecate old software that is still widely in use, the maintainers are always very combative and dont allow any discussions or other opinions. In the end it's a package manager for consumers that hand holds you and is not really useful in a pro context. I've been meaning to jump to macports anyway, maybe ill do it now...
What is the pro vs consumer distinction here? What consumers use homebrew?
On the other side is some consumer who uses brew to install youtube downloader and doesnt care about versions/upgrades, etc...
