Hello vit, r43587 should be backported to ruby_2_0_0, doesn't it? ---------------------------------------- Bug #8623: Make stable Gem::Specification.files in default .gemspecs https://bugs.ruby-lang.org/issues/8623#change-43147 Author: vo.x (Vit Ondruch) Status: Closed Priority: Normal Assignee: drbrain (Eric Hodel) Category: lib Target version: ruby -v: ruby 2.0.0p195 (2013-05-14 revision 40734) [x86_64-linux] Backport: 1.9.3: UNKNOWN, 2.0.0: REQUIRED Although the .gemspec files for default gems are same in function, the different order of their "s.files" makes them different therefore possibly conflicting in multilib scenario. Simple sorting fixes this issue. -- http://bugs.ruby-lang.org/
