[Rails] App behaves differently on Apache and Webrick

[John Johnson]

When running on the Webrick server (script/server), my app works fine. 
When running on Apache 2.0.52, I get the dreaded 'unitialized constant 
Merge' error. Merge is the name of my model, the controller is 
MergesController.

The deadline looms, any help appreciated!

Thanks!
