Engines and rails 2.1.0

Does anyone had issues on running an app using engines under rails 2.1.0?
I had this:

:in alias_method': undefined method initialize_schema_information’ for module ActiveRecord::ConnectionAdapters::SchemaStatements' (NameError) from c:/ruby/lib/ruby/gems/1.8/gems/activesupport-2.1.0/lib/active_support/core_ext/module/aliasing.rb:31:in alias_method_chain’
from P:/sia/vendor/plugins/engines/lib/engines/rails_extensions/migrations.rb:131:in included' from P:/sia/vendor/plugins/engines/lib/engines/rails_extensions/migrations.rb:131:in class_eval’
from P:/sia/vendor/plugins/engines/lib/engines/rails_extensions/migrations.rb:131:in included' from P:/sia/vendor/plugins/engines/lib/engines/rails_extensions/migrations.rb:155:in include’

With engines: = 2.0.0 -

Thanks
