NameError in Rails/infoController#properties ( uninitialized constant ActiveRecord::Base::SQLite3 )
I am trying to setup my RubyOnRails environment as mentioned in the
RailSpace book ( RailsSpace: Building a Social Networking Website with
Ruby on Rails ), pg 18. However when I click on the "About your
application''s environment" link, I get the following :
NameError in Rails/infoController#properties
uninitialized constant ActiveRecord::Base::SQLite3
sqlite3 is setup correctly, I am able to create my own database and
query it.
With Mongrel I get this stack trace :

I am totally new to Ruby on Rails, so have no clue on what to fix.
From the above it appears that I don''t have the SQLite3 environment
setup correctly for Rails. Any idea on what I need to setup ?
Thanks.
