# Install Git on Mac OS X 10.6 (Snow Leopard) Intel x86 (32 or 64 bit)
# by "Matt Di Pasquale" http://www.mattdipasquale.com/
#
# UPDATE: Install Homebrew and run `brew install git` instead of this script.
# Trust me. It's the best. It has a strict policy of only installing files into
# one directory (/usr/local by default). You could just uninstall everything by
# doing `rm -rf /usr/local`. There are many other great things. It just works!
#
# About: This shell script installs the latest version of Git into /usr/local
# because that's the standard directory to install additional software and is
# also recommended by Homebrew (http://mxcl.github.com/homebrew/). This script
# is very similar to the Homebrew Git Formula:
# https://github.com/mxcl/homebrew/blob/master/Library/Formula/git.rb
#
# Note: If you have mysql installed in /usr/local (which you can determine by
# running `which mysql`), I recommend stopping mysql before running this script.
# If mysql is installed in /usr/local but /usr/local/mysql/data doesn't exist,
# manually run `sudo chown -R _mysql:wheel "path/to/mysql/data" after.
#
# Instructions:
#
# 1. Install Xcode (http://developer.apple.com/xcode/).
# 2. Run these Terminal commands to download it to ~/Sources/ & run it.
#    pushd ~/Sources/; curl https://gist.github.com/raw/419201/git-install.bash > git-install.bash; bash git-install.bash; popd
#    Or, download & run this file from the dir in which you store source files.
#   - For 32-bit install, just open git-install.bash and change the occurrences
#     of `-arch x86_64` to `-arch i386`.
#   TODO:
#     Use `arch` command to detect. If not x86_64, warn and allow user to
#     choose via STDIN. If you're reading this right now, that means you're It!
#     Implement & email me update, and you'll fall in love 3 months later! :)
#   - Open Terminal to that directory and run: bash git-install.sh

Quite a few years later, it doesn't seem to work on my side (mac mini 2006, Snow Leopard).
It is more than likely that it is my fault being a total dumb on the Terminal side
