This may be part of your problem.  That call should bring up an error
(not sure why it didn't).  You should be using:

  DB = Sequel.mysql
(db_name, :user=>db_user, :password=>db_password, :host=>db_host, 
:port=>db_port)

Try using the above code and see if it makes a difference.  If not,
add an SQL logger and post again with the output.
