The installation of buildroot failed, see: http://koji.fedoraproject.org/koji/getfile?taskID=3149029&name=root.log
But build phase started, see: http://koji.fedoraproject.org/koji/getfile?taskID=3149029&name=build.log
I'd like to point out that this bug is serious. Imagine, that you have package in C, which is checking by configure installed packages. In buildroot they are missing, but install could be successful because configure detect available packages and use available. Therefore you can have in specfile --with-selinux, but build could be done without SElinux support.
This sounds like a bug in mock to me, file a bug there, imo.
I'm not sure how is mock tested before update in koji. It might be useful to have ticket also here.
I failed ticket also on somewhere else (can't remember where). The solution was update yum-deputils.
yum-utils has been fixed and updated
