I found a simple way ...
yum -y localinstall
http://mirror.its.sfu.ca/mirror/fedora/linux/releases/19/Fedora/x86_64/os...
31.fc19.noarch.rpm
edit /etc/yum.reposd/fedora.repo and fedora-updates.repo
add exclude=sos* to both enabled repos
yum -y install ovirt-engine-setup
all works ... just using sos package from F19
