Hi,

I followed the installation guide on  
[http://technoweenie.stikipad.com/plugins/show/Acts+as+Authenticated](http://technoweenie.stikipad.com/plugins/show/Acts+as+Authenticated),  
but db:migrate fails:

$ rake db:migrate --trace  
\*\* Invoke db:migrate (first\_time)  
\*\* Invoke environment (first\_time)  
\*\* Execute environment  
\*\* Execute db:migrate  
rake aborted!  
uninitialized constant ActAsAuthenticated

Tried to move include AuthenticatedSystem to ApplicationController,  
didn´t help.

Any suggestions?

Regards,  
Martin S.
