Hi,

I have a problem running Mongrel, I’m using the latest ruby 1.9 and  
rails 2.3.5

when I start the server (I’m using Aptana IDE), on mongrel, here is the  
output:

C:/Ruby19/lib/ruby/gems/1.9.1/gems/activesupport-2.3.5/lib/active\_support/dependencies.rb:156:in

Not sure what’s causing the problem, but I think thin and passenger  
are pretty widely preferred over mongrel these days – might want to  
give one of those a shot.
