failed to tag el6 package

I'm the maintainer of the rubygem-asciidoctor package. Thanks to work by Jimmi Dyson, the package now builds successfully for epel6. https://koji.fedoraproject.org/koji/taskinfo?taskID=5552396 However, the el6 build is fails when it tries to tag the release. Do I need some extra permission in order to tag for el6, or is something else wrong? Thanks, -Dan -- Dan Allen | http://google.com/profiles/dan.j.allen
