install hook fails

Often, the install hook fails because of
Unable to find https://cache.ruby-lang.org/pub/ruby/ruby-2.2.0.tar.gz for download, please check your mirror and version

Maybe we can add in some retry logic into the actual fetch of the repo so that it can withstand a bit of internet failure.
