Need help Setting Up Puppet

I am trying to setup Puppet on an Amzon EC2 instance. I am running into some troubles. The procedure I followed is described here: http://wiki.unixcraft.com/display/MainPage/Puppet+3.0+Installation+on+Centos+6.3 Everything pretty much went as per the steps described. Unforntunately Aapache does not start at the end. I get the error: Starting httpd: httpd: Syntax error on line 221 of /etc/httpd/conf/[login to view URL]: Syntax error on line 2 of /etc/httpd/conf.d/[login to view URL]: Cannot l oad /usr/lib/ruby/gems/1.8/gems/passenger-3.0.17/ext/apache2/[login to view URL] into server: /usr/lib/ruby/gems/1.8/gems/passenger-3.0.17/ext/apache2/mo [login to view URL]: cannot open shared object file: No such file or directory I am looking for somebody experienced with Linux to troubleshoot this and get it working. Experience with Puppet would be a plus. A strong Linux experience is a MUST.
