Answer 1

I had a similar problem, and the change involved changing:

@import filename to @import filename.css.sass

Answer 2

I had trouble getting a production server to work (both a local Apache/Passenger setup and the built-in WEBrick server).

The browser was redirected to the 500.html error page, and the log kept saying [GET /] miss. When I reloaded the page repeatedly, eventually I would receive an output similar to what Manish reported.

My Sass files each contained an @import 'base' statement to load common color and font definitions. Changing this to @import 'base.css.scss' and having config.assets.compile = true in config/environments/production.rb made both production servers work.
