Rails app now gives 500 error

I have had my typo site hosted with some other rails apps hosted for sometime with most everything working fine.  I have a fan of one of my apps email me today saying the app is giving them a 500 error.  I check the link:

http://www.thomasonrails.com/warholit/ and sure enough its giving me the error to so I go into a production.log and see something I haven't seen before:
(cutting and pasting this from putty sorry)....
this makes no sense to me and im not sure why my app all of a sudden just started to do this?
any ideas? i can get the full log file and do a better cut and paste if this doesn't help...

You need to configure your database.yml properly.

Thanks , the app never uses or used a database, but I will check the file anyway perhaps it got corrupted.  I do find it strange it just started to give me this error and I haven't touched any thing in it over a year.

Its possible this occurred with an upgrade of Rails and/or RubyGems.  What version of Rails are you running?  Do you have the RAILS_GEM_VERSION line in your environment.rb?  without that it will default to rails 2.0.2 currently.

The RAILS_GEM_VERSION is commented out but says:
1.1.2, should I uncomment it and see if that takes care of things?

Yes, please try uncommenting the line now and see if it helps.
