All,
I am on the page http://bosh.io/docs/install-bosh-init.html and am wondering what's purpose for this section ? Is this for ruby2?

Depending on your platform install following packages:

Ubuntu Trusty

$ sudo apt-get install -y build-essential zlibc zlib1g-dev ruby ruby-dev openssl libxslt-dev libxml2-dev libssl-dev libreadline6 libreadline6-dev libyaml-dev libsqlite3-dev sqlite3
