rspec1 shipped rspec.rb as part of the rubygem-rspec package rspec2 shipped rspec.rb as part of rubygem-rspec-core, so to assist in that migration we left rubygem-rspec at 1.x for the time, and converted packages to depend on rspec-core. When the migration was done, we updated rubygem-rspec. rubygem-rspec was just updated in rawhide to 2.11.0 which again provides rspec.rb (which was removed from rspec-core 2.11.0). So packages just depending on rspec-core will now need to pull in rspec to be able to use rspec.rb The fix is easy enough, just a word of warning if you see related errs in broken builds w/ gem packages starting in rawhide. rspec also depends on an updated version of diff-lcs, which is available in rawhide (thanks mamoru & vit!) -Mo
