Install Puppet 3.x on Amazon Linux AMI

by Keith Hurlic - -

I came across an interesting issue with puppet today. Im using the Amazon Linux AMI
and I discovered that it is running an older version puppet. I did not think much of
it. So I installed the puppet labs yum repo and installed the new shiny 3.7.x version
of puppet. When I did my test run. I received lots of errors which caused me to do
some googling. I finally got everything working. Im posting what I did here in order
to save someone else some time and hair.
