i have installed gems 2.0.2, 1.2.3, 1.1.6  
i need to use version 1.1.6.  
but it seems like its not taking version 1.1.6  
will it take the latest one which which we have installed?

in terminal it shows like this  
sukeerthi@sukeerthi-desktop:~$ gem list | grep rails  
rails (2.0.2, 1.2.3, 1.1.6)

I need to make sure that whether it will take the specific version which  
we  
specify in environment.rb  
Is that is the only means to specify the rails version? or somewhere  
else also we have to specify?

Thanks in advance
