Forum: Ferret Problems with Ruby 1.9.1 / Rails 2.3.2 / aaf

I've set up a debian server with ruby 1.9.1, rails 2.3.2, postgres and
several gems. While I was able to get all my required gems working
(including a patched ferret gem), acts_as_ferret does not work. I've
tried the gem and installed it as a plugin, but either way I get the
following stack trace when I start the web server (I'm also concerned
about the warning "undefining `object_id' may cause serious problem"):

=> Booting WEBrick
=> Rails 2.3.2 application starting on http://0.0.0.0:3000
