Hi,  
I adquired some day ago one Macbook Pro. I installed Rails succefully,  
but now when I try to execute one project I get the next error:

macos:~/Proyectos/locambias vigosan$ rake db:migrate  
(in /Users/vigosan/Proyectos/locambias)  
rake aborted!  
uninitialized constant Locale::System  
/Users/vigosan/Proyectos/locambias/rakefile:12  
(See full trace by running task with --trace)

Plesae, can anybody tell me how can I install locales in Mac Os?

Thanks a lot.
