Ah, this is my failt. There's a rails 2.2.3-1 package (which of course includes ActiveRecord and ActiveSupport), and there are libactiverecord- ruby and libactivesupport-ruby 2.3.2 packages, and I had all of them installed. Removing libactiverecord-ruby and libactivesupport-ruby solved this problem.
