Wget install instructions may not work

[lowlevelsoul]

If the user does not have ssl already installed, the wget installation step will fail. I'd suggest an alternate path of installing wget via brew to manage install dependancies.

First install brew;
ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install

Use brew to install wget with ssl;
brew install wget --with-libressl
