I want to use the CSV module with rails 3.2.1 on heroku cedar, but

require 'CSV'

doesn't works

here is the error when testing with the console:

try

require 'csv'

it's case sensitive.

UPDATE: This isn't a Heroku problem mind you - if you did the same locally you'd get the same eror. CSV is in the standard library in Ruby 1.9.
