Ruby (Rack) Application Could Not be Started... again

Question

Not sure where to start to look. Ive looked at the files mentioned in the backtrace but not seeing any problems with them. Maybe another set of eyes can see something I dont. Heres the backtrace:

The application has exited during startup (i.e. during the evaluation of config/environment.rb). The error message may have been written to the web servers log file. Please check the web servers log file (i.e. not the (Rails) applications log file) to find out why the application exited.
If that doesnt help, then please use the backtrace below to debug the problem.

The error message tells you to look in the web server error log file. Did you look in there? What is in the file?
