Cannot activate feedtools gem due to frozen rails install

I got feedtools 0.23 installed. I am trying to familiarize with the gem
but when i do “require ‘feed_tools’” in script/console of the app, i get
this:
Gem::Exception: can’t activate activerecord (>= 1.10.1, runtime),
already activated activerecord-2.1.0

The app has rails 2.1.0 frozen and I have rails 2.2.2 installed on the
system.
How would I troubleshoot this?

This is a known issue with the 2.1 series - see
http://rails.lighthouseapp.com:80/projects/8994/tickets/1107
for details. If at all possible, I’d recommend that you upgrade to
2.2, which
fixes the issue.
