Rails - Sep 2008 - config.gem vs require 'somegem'

I am very confused by the config.gem statement in 2.1

If I put config.gem ''pdf-writer'' in my environment.rb I get
the
following error when I try to instanciate a PDF object in my
controller with the statement pdf = PDF::Writer.new

uninitialized constant CollectionsController::PDF

so I try putting require ''pdf/writer'' in my environment.rb and
the
application fails to load with:

no such file to load -- pdf-writer /usr/local/lib/site_ruby/1.8/
rubygems/custom_require.rb:27:in `gem_original_require'' /usr/local/lib/
site_ruby/1.8/rubygems/custom_require.rb:27:in `require'' /usr/lib/ruby/
gems/1.8/gems/activesupport-2.1.0/lib/active_support/dependencies.rb:
509:in `require''
etc
..

The gem is in my vendor directory.
I would like to get to the bottom of this as I have had similar
problems with gems in the past and I dont really understand whether I
still need a ''require'' when I have the
''config.gem''

Cheers
George

Same problem for me.

I have installed ''rubyist-aasm'' for restful_authentication,
but when I
insert config.gem ''rubyist-aasm'', I get an error message.
