DrbServer incompatible with config.gem

[Chris G.]

I don't use the AAF gem, but do have a require statement in a
initializer in config/intializers that pulls in acts_as_ferret. Any
chance you can supply a more detailed back trace that sheds some light
on what class is causing trouble? Do you also have trouble booting
script/console?

I recently upgraded to Rails 2.2.2 and refactored some of my rails code
to use the config.gem functionality. In doing so, I noticed some odd
behavior when trying to start the DrbServer. Essentially, the DrbServer
will not start unless I have the "require 'acts_as_ferret" statement
below in environment.rb. I thought the gem.config would have been
enough, but apparently not.
-- start environment.rb --
Rails::Initializer.run do |config|
[...]
# Requires acts_as_ferret must be here, can't figure out why
require 'acts_as_ferret'
config.gem 'acts_as_ferret', :version => '0.4.3'
config.gem 'ferret', :version => '0.11.6'
[...]
end
-- end environment.rb --
Here's the error message I receive when the require is left out.
-- error --
undefined method `acts_as_ferret' for #<Class:0x22f9bec>
-- end snip --
Any ideas if this is normal?
