Problem using DBMS_PIPE

Hello,

I am trying to use DBMS_PIPE package for the first time, with little success. When I attempt to create the procedure that utilizes this package, certain procedures (create_pipe, send_message, receive_message) are not recognized and I get the following messages

PLS-00221: 'CREATE_PIPE' is not a procedure or is undefined PL/SQL: Statement ignored
PLS-00221: 'SEND_MESSAGE' is not a procedure or is undefined PL/SQL: Statement ignored
PLS-00221: 'RECEIVE_MESSAGE' is not a procedure or is undefined PL/SQL: Statement ignored

On the other hand, certain procedures _are_ recognized (pack_message, receive message). No error msg is received on these calls.

Furthermore, if the offending lines are commented out and the procedure is compiled and run, the expected --

ORA-06556: the pipe is empty, cannot fulfill the unpack_message request

is received, reinforcing the notion that DBMS_PIPE.unpack_message exists.

To the best of my knowledge, all of the appropriate scripts have been run (catproc.sql, standard.sql, and all of the dbmsxxxx.sql scripts including dbmspipe.sql). Also, I believe the appropriate priv's have been granted .

Thanks in advance for any help you might be able to provide,
