No one was able to answer Carl Mercier's question:

I am trying to use sqlite3 for my dev database with my Rails app (1.2rc2). I am on OS X so sqlite3 is installed by default (I even installed the lastest version with darwinport), and I have done gem install sqlite3-ruby.

However, when I try to do anything that has to do with ActiveRecord, I get errors. Here's an example:

>> Domain.new
ActiveRecord::StatementInvalid: ActiveRecord::StatementInvalid

Any idea?

EDIT: The funny thing is that I use sqlite3 and it works great with another project I started some time ago...
