What's the best way to install command line utilities such as GIT? I'm a Windows/Linux guy that just got my Macbook Air. I do web dev, and am currently trying to setup this machine for some on-the-go development.

After some research attempts, I'm wondering: what's the best way to install command line utilities in Lion, such as GIT? Best as in easiest to install, maintain, upgrade etc.

As I understand it, there are some alternatives: macports, homebrew etc. Or in the GIT example, maybe just download the installer from their website.

Thanks.
Git's bundled with the free version of Xcode 4 on the app store. That's about as easy and official as it gets in my book. You won't do wrong by choosing homebrew as it's solid and got great momentum plus mindshare presently.
