I have just upgraded installed rails 1.1 using gem. I have set up a  
rails app using radrails. I have set up one model for testing and set  
up one migration in order to create the table for that model. When I  
type rake migrate I get the following error message.

rake aborted!  
uninitialized constant WEBrick

(See full trace by running task with --trace)

I have attached the trace below.

This happens both on windows and Centos 4.2. I am using mysql 4.x.  
Anybody have a clue?

\*\* Invoke migrate (first\_time)  
\*\* Invoke db:migrate (first\_time)  
\*\* Invoke environment (first\_time)  
\*\* Execute environment  
rake aborted!
