Hi,

I installed rails3 on my mac and after installing 2.3.5 using gem  
install rails -v 2.3.5, if I run gem list rails, I got  
\*\*\* LOCAL GEMS \*\*\*

rails (3.0.0.beta, 2.3.5)

But if I run  
rails _3.0.0.beta_ test  
got the following error  
can’t find executable rails for rails-3.0.0.beta (Gem::Exception)  
from /usr/local/bin/rails:19:in `’

How can I create rails3 project?

Thanks
