computed field <str> in relation <str> not IMPORTed

  Explanation:  You specified a computed field  in  your  database
  that  could not be imported.  Perhaps the field references other
  fields and relations that were deleted from the database  by  an
  older  version  of the software that would have permitted such a
  thing.

  User Action:  You must investigate  the  problem  further.   The
  relation  should  have  been  properly  imported  except for the
  listed field.
