remove_column fails with sqlite3

See Railsforum post for more details but the reproduction is simple in rails 1.2.5:

rails testmigrations --database=sqlite3

cd testmigrations

ruby script/generate scaffold_resource person first_name:string last_name:string

ruby script/generate migration remove_last_name

Edit the migration:

class RemoveLastName < ActiveRecord::Migration
  def self.up
    remove_column "people", "last_name"
  end

  def self.down
    add_column "people", "last_name", :string
  end
end

rake db:migrate

no problem

rm db/development.sqlite3

ruby script/plugin install svn://errtheblog.com/svn/plugins/sexy_migrations

rake db:migrate --trace

kaboom:

** Invoke db:migrate (first_time)

** Invoke environment (first_time)

** Execute environment

** Execute db:migrate
