Advanced queuing : dequeing from remote database

I am experimenting with advanced queueing in Oracle 9i and am able to
enqueue and dequeue messages within the same database.
However I would like to dequeue messages on a remote database via a database
link.
I am confused as to what I need to set up on the remote server in order to
dequeue the message.
I have set up the database link that points back to the enqueueing database,
The database link works OK.
I am then trying to dequeue the message on the remote database using the
following code(which is the same I use when doing this all on the same
database except for the references to the database link). I get the error :
message opd4678.new_job_message@DEMO;
*
ERROR at line 6:
ORA-06550: line 6, column 34:
PLS-00331: illegal reference to OPD4678.NEW_JOB_MESSAGE@DEMO
Any ideas what I have done wrong?
