NoMethodError: undefined method `mount_uploader'

[Rick]

There may be a simple solution for this, but I can't seem to get my
app going with carrierwave. I'm running on Rails 2.3.5, latest
carrierwave and using Mongoid for my ORM. I'm just using the console
to create a new object with Photo.new when the following is thrown:

NoMethodError: undefined method `mount_uploader' for Photo:Class

Here is a gist of my model and uploader: http://gist.github.com/290836.
Any help is appreciated. Thanks!

Which version of carrierwave and which version of Mongoid?

[Rick Salsa]

The latest gems of both. Thanks!

So it seems I was running carrierwave 0.4.3 which was the problem. I'm running 0.4.4 now and all is working thus far.
