sunspot/sunspot — Issue #148: more_like_this resulting in exception

I'm trying to get ```more_like_this``` to work, but I'm getting this error:

undefined method `more_like_this_fields' for nil:NilClass

Here is my searchable config:

searchable do
integer :id
text :title, :boost => 5, :more_like_this => true
boolean :hidden
integer :site_id
end

Here is my call to more_like_this:

@posts = Sunspot.more_like_this(post) do
fields :title
with(:site_id, post.site.id)
with(:hidden, false)
end

Here's a full trace:
