I think this just means that certain methods called in the application are currently deprecated (i.e., in a future release they won’t perform any action and may not even exist and hence raise an error). All the deprecation warnings shown there are warning you that in rails 2 they will be deprecated so as long as you are using rails \< 2 (i.e., rails \< edgerails) you won’t have any problem. Does the app actually start? Are you using the latest release version of rails (1.2.3)? On Aug 6, 9:18 am, Yin S. [removed\_email\_address@domain.invalid](mailto:removed_email_address@domain.invalid)
