Posted this to the rails group as well. Found that upgrading to Rails  
1.1.1 and the engines plugin 1.1.1 caused web server to not start. The  
solution turned out as follows:

The following code is in the new version of engines.rb:

begin  
require ‘rails\_version’ # Rails 1.0, 1.1.0  
rescue LoadError  
require ‘rails/version’ # renamed as of Rails 1.1.1  
end

but the exception from starting the web server is (Gem::Exception) from  
the trace. Changing the above  
to

begin  
require ‘rails\_version’ # Rails 1.0, 1.1.0  
rescue  
require ‘rails/version’ # renamed as of Rails 1.1.1  
end

allows the web server to start.

This error only seems to occur if you have BOTH Rails 1.1.0 and 1.1.1  
gems installed (which is why I couldn’t replicate it before).

It has been fixed in the official release, please update or reinstall  
your version of the Engines plugin.

Cheers
