uninitialized constant Refinery::Blog::Post::FriendlyId

I'm adding refinerycms-blog to my existing Rails 3.2.8 app. I've got refinerycms-blog (2.0.4) bundled. Generation step worked fine but when I try to run the generated migrations I see:

rake aborted!
An error has occurred, this and all later migrations canceled:

I got around this by adding
require 'friendly_id'
to the migration with the problem, but thought I'd send this your way to get some insight on the problem.
