Yes, actually my workaround is a perl script that looks through the
dump and cleans all the tablespaces definitions, doing this on the
index file sure is a better approach, I am working on this right now,
but wish I could do this using only oracle standard tools
Looks like even the new data pump ultility have some limitations
regarding lobs and raw data types
