Thanks for your reply. Any idea what could be the reason?

Well, what's on those lines in the routes file that it's complaining
about? Is there something inappropriate going on with a Hash?

Best,

In routes.rb file, here are the corresponding lines:
Line 1: ActionController::Routing::Routes.draw do |map|
Line 53: map.with_options(:controller => "item", :conditions =>{:method
=> :put}) do |m|
Line 58: m.move
'/item/move/:relation_type/:item_type/:item_id/:source_type/:source_id/:dest_type/:dest_id.:format',
:action => 'move'

I don't think there is anything to do with Hash in those code...

it looks (as a guess) that the call to move, instead of tumbling
through to method_missing and created a named_route is calling a
method defined by rake. Does changing the name of the route make any
difference?
