Description of problem:

Trying to walk an RDO install on RHEL64 as a RHEL customer might.  The install works following different steps, but I *think* this should be addressed..

 package: rubygem-json-1.5.5-1.el6.x86_64 fails to install due to a dep on rubygems.

Only ruby193-rubygems is available.

1. install RHEL6.4
2. register and subscribe RHEL6.4 to subscription-manager 
3. yum install http://repos.fedorapeople.org/repos/openstack/openstack-havana/epel-6/rdo-release-havana-6.noarch.rpm
4. I have epel installed but I don't think is relevant here.
