Strange error when running as DRb

I’m getting an error that seems to be unique when trying to run ferret
as a DRb in conjunction with acts_as_ferret.

Locally, I can run in production mode with ferret running as a DRb and
everything works great. When I transfer my project to my host, things
begin to fall apart.

Running ferret remotely as a DRb appears to work just fine, but
‘mongrel_rails start’ produces:

** Starting Rails with production environment…
load_missing_constant': uninitialized constant Ferret::Store (NameError) from /home/223/data/rubygems/gems/gems/activesupport-1.4.2/lib/active_support/dependencies.rb:452:inconst_missing’… + more levels

Has anyone encountered a similar Ferret::Store error?
