Um. Don't run the installation instructions.

While the download itself is served using https (from amazon), curl will contact the google url shortener using HTTP. Honestly, if I wanted to MITM one thing on any network, URL shorteners would come first.

Edit: The website switched from googles link shortener to git.io (http) and download to github downloads. git.io's https version seems to have certificate issues.
