Standard setup according to  
[rails.info](http://guides.rails.info/getting_started.html) and the blog posts I found  
on the subject. Anyway when trying to run the RAILS SERVER command I  
receive the following error. I can’t fix it for now and I hope someone  
can help.

This is the error log:

Damn! 🙂

It works now. Maybe someone should update the guidelines to say  
1.9.2-head

Thanks a lot!

Try using ruby 1.9.2-head instead of preview1:

> rvm install 1.9.2-head

That’s how it solved this problem for me.
