This has been completed and building is back to normal. please report any odd failures. there has been a very large change in koji. noarch subpackages are now supported, which needs srpms to be built in a chroot. the last of F-11's features that needed koji chanes are now ready to deploy.
I'm not sure if this is related but I'm having issues building in plague for EPEL:
http://buildsys.fedoraproject.org/logs/fedora-5-epel/1529-pyodbc-2.1.4-3.el5...
Seems like python is missing from the buildroot there? I've double checked and rebuilt my package under my own mock environment a few times so I'm really hoping this isn't a goof on my part....
