in this commit: RubyGems now automatically checks for gem.deps.rb or Gemfile when running ruby executables. This behavior is similar to `bundle exec rake`. This change may be reverted before Ruby 2.1.0 if too many bugs are found. * test/rubygems: ditto. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@43767 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
