Setting the GEM_PATH after ruby is started is not reliable enough. In
some cases rubygems would have already loaded and ignore these settings.
Fixes#14048
After ruby initializes, rubygems no longer reads the GEM_PATH. Before,
we have the following scenario:
Gem.path # => ["a"]
ENV['GEM_PATH'] = ["b"]
Gem.path # => ["a"] # Still returns the same
Gem.use_paths is the documented way to create isolated environments as
documented in [1].
[1] http://www.rubydoc.info/github/rubygems/rubygems/Gem.use_paths
The idea is to bundle ruby, bundler and bundix together. I was
having issues where bundler was installed with ruby 2.3.0 and I wanted to use
ruby 2.0.0.
With this change all the developer has to do is install `ruby_2_0_0.dev`
either in his environment or in a nix-shell.
