You could try using --skip-broken to work around the problem
You could try running: rpm -Va --nofiles --nodigest
Puppet looking for rubygems package and in the RHEL 6.5 repo all of a sudden there is this rpm for Red hat Enterprise Linux 7 (el7), rather than for version 6 (el6) !!
# yum info rubygems

Even though rubygem 2.4.8 was also installed on the server, it still asking for rebygem is a dependency:
# gem --version
2.4.8
Ended up that culprit were both Puppet that asking for rubygems while is is already installed and Redhat that putting wrong rpm architecture in its repository. (rubygems-el7 on el6 repository).
Eventually I manually downloaded and installed rubygems rpm for el6 (rubygems-1.3.7-5.el6.noarch.rpm) and Puppet installation went smooth this time. But it takes a while to figure it out though.
