`const_missing': uninitialized constant

Hi all,
still the same error, when accessing my model childs on the site5 server
…(Person.infogroups.first.infoattributes, (a Person has_many
infogroup which has_many info_attribute))

I double check my config and the server and it is exactly the same
(except for rubygem which is for me 0.8.11).

==>>ERROR
usr/lib/ruby/gems/1.8/gems/activesupport-1.3.1/lib/active_support/dependencies.rb:100:in
`const_missing’: uninitialized constant

Is it a rails bug ?
thanks
