Help with iDate

All,
I have installed the iDate utility and the Select iDate(Date...) function
works fine, but when I try to use the ConvertToiDate function, I get the
following message:
Message ID . . . . . . : SQL0204 Severity . . . . . . . :
30
Message type . . . . . :
Diagnostic


Message . . . . : CONVERTTOIDATE in *LIBL type *N not
found.
Cause . . . . . : CONVERTTOIDATE in *LIBL type *N was not found. If
the
member name is *ALL, the table is not partitioned. If this is an ALTER
TABLE
statement and the type is *N, a constraint or partition was not found.
If
this is not an ALTER TABLE statement and the type is *N, a
function,
procedure, trigger or sequence object was not
found.
If a function was not found, CONVERTTOIDATE is the service program
that
contains the function. The function will not be found unless the
external
name and usage name match exactly. Examine the job log for a message
that
gives more details on which function name is being searched for and the
name
that did not
match.
Recovery . . . : Change the name and try the request again. If the
object
is a node group, ensure that the DB2 Multisystem product is installed
on
your system and create a nodegroup with the CRTNODGRP CL command. If an
external function was not found, be sure that the case of the EXTERNAL NAME
on the CREATE FUNCTION statement exactly matches the case of the name
exported by the service program.

When I check the results of the create program for iDate, I see the
messsages:
SQL7997 0 105 Position 3 Function CONVERTTOIDATE was created in
R37MODSC77.
SQL7997 0 116 Position 3 Function CONVERTTOIDATE was created in
R37MODSC77.
The library containing the service program *is* in my library list.

I am on V6R1M1.


Thanks,
