I upgraded from Snow Leopard.

Git went missing, so I downloaded the .dmg and installed it: http://code.google.com/p/git-osx-installer/downloads/detail?name=git-1.7.6-x86_64-snow-leopard.dmg&can=2&q=

Uninstalled my current devtools: sudo /Developer/Library/uninstall-devtools

Installed Xcode via the App Store.

[remote "origin"]
	fetch = +refs/heads/*:refs/remotes/origin/*
	url = [email protected]:joyent/node.git

Now add the line fetch = +refs/pull/*/head:refs/remotes/origin/pr/* to this section. Obviously, change the github url to match your project's URL. It ends up looking like this:
