puppet RPM version conflict
The below puppet error occurred. Despite the usual unhelpful reference to a ruby script, it turned out that the Puppet V3 client had been automatically uninstalled and replaced by puppet-agent.
Normally, you can easily force certain versions of a particular package, however in this situation, PuppetLabs have reverted to earlier behavious and labelled the package "puppet-agent", whilst obsoleting the "puppet" package. This meant that ordinary steps to force a certain version to be installed didn't work.
I was able to manually work around it by using "yum install --exclude puppet-agent*"
This was caused by making both the Puppet V3 and Puppet V4 packages available in the same RPM Repo (as there is a need for both versions of the install during a transition period)
The Error
[root@puppet-client ~]# puppet agent -t
Warning: Setting 'pluginsync' is deprecated.

(This is the Puppet V4 client package)
