Your package mono-bouncycastle failed to build from source in current rawhide. http://koji.fedoraproject.org/koji/taskinfo?taskID=5716081 Build logs: root.log: http://kojipkgs.fedoraproject.org/work/tasks/6081/5716081/root.log build.log: http://kojipkgs.fedoraproject.org/work/tasks/6081/5716081/build.log state.log: http://kojipkgs.fedoraproject.org/work/tasks/6081/5716081/state.log NOTE: build logs are cleaned up after 1 week For details on mass rebuild see https://fedoraproject.org/wiki/Fedora_20_Mass_Rebuild
The build fails on arm because of missing build dependency on nant. Looks like nant just needs bootstrapping; at least it's not marked as ExcludeArch on arm. Marking nant's FTBFS bug as blocking this one.
This bug appears to have been reported against 'rawhide' during the Fedora 20 development cycle. Changing version to '20'. More information and reason for this action is here: https://fedoraproject.org/wiki/BugZappers/HouseKeeping/Fedora20
