PLS-00907: cannot load library unit

Question

I have a problem with a stored procedure that runs via cron to insert records into a large partitioned table. This was running fine until a week back it stopped working.
The error it mentioned during execution is
PLS-00907: cannot load library unit
MET.CLINICAL_DATA (referenced by MET.INSERT_CLINICAL_DATA)
MET is the owner of the CLINICAL_DATA table and the INSERT_CLINICAL_DATA procedure. This procedure is run by a user called MET_USER who has an execute privilege on MET's INSERT_CLINICAL_DATA and its tables.
So what might have caused this error. I did spend atleast 2 hours looking in the metalink and as those articles mentioned, I am neither using a database link here nor I am calling a remote procedure.
Any thoughts?
Thanks

No, not to my knowledge. But I do have another stored procedure that also runs everyday that has got DDL statements on the CLINICAL_DATA table. Some of the DDLs in that are ----
execute immediate 'alter table clinical_data drop partition part' || part_rec_l.id || ' update global indexes';
execute immediate 'alter table clinical_data split partition ' || 'last_values at ( ''' || (temp_day_l * ms_per_day_l)|| ''') into (partition part' || new_id_l
|| ', partition last_values) update global indexes';
execute immediate 'alter table clinical_data modify partition '|| 'part' || new_id_l || ' rebuild unusable local indexes';
execute immediate 'alter table clinical_data modify partition ' || 'last_values rebuild unusable local indexes';
Thank you
