I am a newbie to engines, I will need some advices.  
I am developing a new applications with edge rails.  
I pretend to use datebocks engine, and I will try to install first the  
new engines plugin.  
Is this ok?

I asm trying to install the plugin with the command:

./script/plugin install  
ttp://svn.rails-engines.org/engines/branches/rb\_1.2

but I have this error with the installation.

I thougt that this was not a big problem. It seems only showing a  
warning message based on the version of rails I use.  
But then I have errors running my tests from radrails.
