RoR, apache, passenger deployment problems

[Pete Stieber]

I'm trying to deploy a sample ruby on rails application on Fedora 20. 
The application runs locally using WEBrick.  I have the 
mod_passenger-4.0.18-4.fc20.x86_64 package and the associated ruby gems 
installed.  I'm very new to this so I'm sure I'll be asking some stupid 
questions.

The first thing I notice is complaints in /var/log/httpd/error_log when 
restarting apache with passenger setup.  I've attached the relevant 
error_log content.  I googled, but couldn't find a clear answer.

Can someone help me out?

Pete
