In the short run yeah. You have a point. I intend to uninstall & reinstall everything once Homebrew is officially supported though, which isn't a big deal for me (and I actually kind of enjoy building from source just for the experience).

But these replies are making me think that a large part of my decision to do this is motivated by me just not understanding Homebrew well enough (e.g. how easy it is to nuke everything). Oh well, we'll see how it goes.
