Rails @import compass not found

Here is my application.css:

/*
 * This is a manifest file that'll be compiled into application.css, which will include all the files
 * listed below.
 *
 * Any CSS and SCSS file within this directory, lib/assets/stylesheets, vendor/assets/stylesheets,
 * or vendor/assets/stylesheets of plugins, if any, can be referenced here using a relative path.
 *
 * You're free to add application-wide styles to this file and they'll appear at the top of the
 * compiled file, but it generally better to create a new file per style scope.
 *
 *= require_self
 *= require_tree .
*/

@import "compass/reset";

Getting 404 on compass reset:

GET http://0.0.0.0:3000/assets/compass/reset 404 (Not Found)

BTW, launch of Rails 3.2.3. Thank!
