Rails - Oct 2008 - oracle_enhanced adapter 'uninitialized constant' error

Hi,

Can any one help me? I''m using Ubuntu and trying to connect to an
oracle
database using oracle_enhanced adapter connection, but keeps getting
following error:

/usr/lib/ruby/gems/1.8/gems/activesupport-2.1.0/lib/active_support/dependencies.

Any ideas from any genius?
