Rails - Aug 2006 - Dependencies.rb issue

I am testing the 1.1.6 on a new server that we were going to migrate  
to and have run into an issue with loading the sentry plugin. I think  
it has to do with the changes to dependencies.rb but not sure. I have  
Sentry set to load the key directories in the environment.rb file and  
on server start I receive a `const_missing'': uninitialized constant  
Sentry (NameError). This is working fine on all our testing and  
production boxs where we have not upgraded. from 1.1.2

Any thoughts on what is going on?
