Hello RoR Developers,

I have problem with rake, I got gettext.rake(“lib/tasks”) something like

desc ‘Create mo files’  
task :createmo do  
require ‘gettext/utils’  
require ‘gettext/rails’

```
GetText.create_mofiles(true, 'po', 'locale')

```

end  
end

when I try to use it,gives me error like,  
rake createmo

(in C:/…/rails)  
rake aborted!  
Don’t know how to build task ‘createmo’

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

what can I do now? what is the problem here…
