Apache 2.2 and dispatch.cgi woes

Hi all,

I have a RAIL/Activerecord/Postgres application working with webRick. I
have configured apache to have
a virtual host on a separate port.

But, when I launch the application with apache cgi using ruby
dispatch.cgi, I have the following error
message (Any clue ?):
NameError in ActeurController#list

uninitialized constant PGconn

RAILS_ROOT: /export/home/videorail/public/../config/..
