An error occurred when receiving wrapped code for the 'LOCUS.INC' object: ORA-06550: line

An error occurred when receiving wrapped code for the 'LOCUS.INC' object: ORA-06550: line

I get this error when I do a schema compare between 2 databases.

An error occurred when receiving wrapped code for the  'LOCUS.INC' object: ORA-06550: line 13, column 37:
PL/SQL: ORA-00942: table or view does not exist
ORA-06550: line 13, column 7:
PL/SQL: SQL Statement ignored.

I cannot get past this and do not know where to start looking.
