The wget lesson that I wrote needs to be updated to reflect new installation instructions.

From an e-mail I received:

You have:

ruby -e "$(curl -fsSL https://raw.github.com/mxcl/homebrew/go)"

Not only did that not work, but the Homebrew site (https://brew.sh) now suggests this:

/usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"

I will explore this when I find a chance either today or early next week, and can stage a PR for the PH team's review.
