def has_rubygems?
  # Gems are not actually available when Bundler is loaded, even
  # though the Gem constant is defined. This is because Bundler
  # loads in rubygems, but then removes the custom require that
  # rubygems installs. So when Bundler is around we have to act
  # as though rubygems is not, e.g. we shouldn't be able to load
  # a gem that Bundler doesn't want us to see.
