rubygem-rack-accept fails to rebuild from source. See build failure at https://brewweb.devel.redhat.com/taskinfo?taskID=4104046 for details.
Missing build dependency Error: No Package found for rubygem(test-spec) Looks like it was originally built against rubygem-test-spec-0.10.0-3.el6_0 per http://download.devel.redhat.com/brewroot/packages/rubygem-rack-accept/0.4.3/6.el6_0/data/logs/noarch/root.log I'm tagging that version back in to ce-rhel-6-candidate.
rubygem-rack-accept-0.4.3-6.el6 successfully rebuilt on x86_64 (the only arch where this package is shipped with CloudForms-1.0). Closing out.
