Hello,

I''m having an error that occurs in production (on Dreamhost) but does
not occur in development on my local machine. The situation is that
there is a model (Article), and it uses act_as_ferret for search. The
error is as follows (where I say {full server path}, that''s not what
the error says, just my note):

LoadError (Expected {full server path}/article.rb to define Article):

For this app, Rails is frozen at 2.0.2. All gems are included in /
vendor. Any help would be most appreciated. Thanks.
