switching between different versions of ruby and rails

hi guys,
??I've had very little luck with RVM to switch between different versions of ruby and rails on my Mac. ?I installed ruby 1.9 with mac port and updated to rails 3 to upgrade my app. ?However my current app only works with rails 2.3.3. ?So I installed RVM to manage the versions but it doesn't seem to work for me. ?It doesn't produce any error but somehow does not want to do the job. ?Any idea? ?Any other alternatives to switch between different versions without RVM? ?or is there something wrong with my RVM? ?Any help would be appreciated!
