"insufficient privileges" means a grant is missing for the user your importing into. If this is a copy from one DB to another just compare the sorce user to the destination. Grants from the SYS schemas are not exported because SYS is not exported you will have to script these grants as needed.
For example grant sleect on v_$process to fred; whilst connected as "/ as sysdba".
