I just finished writing this, and everything seems to be working fine. I used
the newer oracle_create.sql that was just posted here. You may want to remove
the comments from that SQL script because they make loud and obnoxious error
messages. In imp/config/defaults.php3, you'll want to switch db_driver to
'oci8'
