if you are using transportable table spaces then you should include the parameter "transport_datafiles" in your impdp command.
Also, what Oracle Database release are you using ?
What is 'IS_IMPORT_TRANSPORTABLE'? Is it an obect in your database?
sql> select * from dba_objects where object_name='IS_IMPORT_TRANSPORTABLE';

I suspect some objects are invalid in the dictionary - can you re-run catalog.sql and catproc.sql to see if that resolves it?
