hi guys:
I am trying to use mock to build fedora 19 on mips machines, the base system can work ,
so I got some errors while building some src.rpm on koji. (not familar to fedora)
Enviroment:
kojihub  and kojira are running on the same host ( a x86_64)
kojid on a mips machine.
=================================
when I ran "mock --rebuild some.src.rpm", I got errors on building build root enviroment.
It seems something wrong with yum on the base system.
any suggestion ? thx. I am sure the deps is ok , there's required package in the repo made by koji regen-repo.

root:/usr/lib/rpm# yum --installroot /var/lib/mock/fc19-mipsel-build-1-2/root/ groupinstall build
There is no installed groups file.
