Steps I took to install wget on my OSX box.
$ /bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)
ADD homebrew to your PATH:
$ (echo; echo 'eval "$(/opt/homebrew/bin/brew shellenv)"') >> /Users/tgrubbs/.profile
$ eval "$(/opt/homebrew/bin/brew shellenv)"
$ brew install wget
