I'm trying to import the NGS database using the dump from ftp://ftp.musicbrainz.org/pub/musicbrainz/data/ngs/20100616/
The INSTALL document says that I only need mbdump and mbdump-derived. After trying to import them with ./admin/InitDb.pl --createdb --import ~/Downloads/mbdump* --echo
I get an error:

Error during sql/CreateFKConstraints.sql at ./admin/InitDb.pl line 92.

which indicates maybe that I need the editor data too?
