Building an ultrasonic sensor backpack

Note: This is a bit of a scratch to see what's involved in getting the ping sensor to work as an I2C backpack.

Compiling v8 and Hello, World Example on Mac OSX Mavericks (10.9.4)

by Keith Rosenberg (netpoetica)

Note: do this in some sort of project/ directory that makes sense. depot_tools are going to need to be in your path, so you may want to install them somewhere you are comfortable with.

1) Get the v8 source

git clone https://github.com/v8/v8.git

2) Install depot tools
