Description of problem:
when I attempt to install puppet on a brand new rhel6.1 system, it cannot do so because it cannot find a package that meets the dependency on ruby(selinux).  

Version-Release number of selected component (if applicable): 0.25.5-1.el6


How reproducible: install a brand new system using the minimal package set.  register the system with rhn, and run yum update.  install the epel rpm for rhel6.  attempt to install puppet using yum.

Actual results:
[root@localhost ~]# yum install puppet
Loaded plugins: aliases, downloadonly, product-id, rhnplugin, subscription-manager, tmprepo

 You could try using --skip-broken to work around the problem
 You could try running: rpm -Va --nofiles --nodigest
[root@localhost ~]# 

Expected results:
puppet installs.
