Xcode – Does Xcode 4 install git

I bought a new MacBook Pro and installed the applications list below in order. On my old MacBook, also running OS X 10.6.6, I didn't have /usr/bin/git, however, on the new MacBook Pro, I do. The only differences that I can think of between the two systems are:

1. New MacBook Pro has Xcode 4 vs. Xcode 3 on old MacBook
2. New MacBook Pro installed git using homebrew vs. old MacBook installed [git-osx-installer][]

Homebrew installed git 1.7.4.1 into /usr/local/Cellar/git and symlinked it into /usr/local/bin. This leads me to believe that Xcode 4 installed git 1.7.3.4 into /usr/bin. Can anyone confirm or deny this?

If Xcode 4 didn't install git 1.7.3.4 into /usr/bin, any thoughts what program did?

Update: Package Receipt Info

I ran pkgutil --file-info /usr/bin/git and the following info was displayed. This appears to incriminate Xcode 4.

volume: /
path: /usr/bin/git

pkgid: com.apple.pkg.GitLeo
pkg-version: 4.0.0.9000000000.1.1248867338
install-time: 1300459157
uid: 0
gid: 0
mode: 755

Why It's a Problem that Xcode 4 Installs git

By default, the path /usr/local/bin is after /usr/bin (see the file /etc/paths). This means that git 1.7.3.4 is used instead of 1.7.4.1 that Homebrew installed.
