I'm slightly confused under Lion as to how to get dependencies in place for Homebrew. It wants Xcode in place, and I can go to the app store and click on "Install", and it dutifully says "Installing"... and stays stuck on "Installing" after several minutes. I can find Xcode but apparently not get to "Installed", in the past indicative.
How can I install Xcode? Do I just need to give it more time to install? Or is there another way like installing from tarball? It's been "Installing" for a few minutes, and seems stuck.
