Depends on how you installed it in the first place. If you used the gem

gem update rails --include-dependencies and then change the gem version  
accordingly in environment.rb.

but doesnt the app use the old gem?. because in boot.rb is something  
like  
RAILS\_VERSION=‘1.1.4’ and this is not updated by installing a new gem
