Standard setup according to rails.info 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:
environment.rb has changed and many things has been moved to initializaers. This blog post might help:
I will check it. Thanks!
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.
Damn! 
It works now. Maybe someone should update the guidelines to say 1.9.2-head
Thanks a lot!
