Subject: Strange error: QtRuby and AR (sqlite3)

I'm developing a recipe app for my wife using ActiveRecord (with
sqlite3) and QtRuby. It "works" on my iBook, but when I try to test it
on my Debian sarge box I get the following:

/usr/local/lib/site_ruby/1.8/rubygems.rb:172:in `method_missing':

Line 31 of qt.rb is simply

    recipes = Recipe.find(:all)

which doesn't really match the error at all.

ActiveRecord is installed via gems, and rails on this box is working
fine (lam.fugal.net - also using sqlite3). QtRuby is installed by hand
(version 1.0.9) and it works fine as well. When I fire up irb and load
everything but the gui by hand I can see and use the db via AR just
fine. I'm completely confounded, and I think it might be something
deeper like maybe QtRuby and gems (or at least the AR version from
gems) not playing nicely, even though it works fine on my laptop.
(There I also have qtruby from hand, AR and sqlite3 from gem)
