Your package rubygem-scoped_search failed to build from source in current rawhide. http://koji.fedoraproject.org/koji/taskinfo?taskID=5772032 For details on mass rebuild see https://fedoraproject.org/wiki/Fedora_20_Mass_Rebuild
This is due current rebuild of rails (to rails 2.0). And rails deps are broken. I will have to wait till the rebuild is done.
