I think you still haven't cleaned your DB. The steps are the following (the ones I use at least):
shutdown your aolserver
dropdb widge4
createdb widge4
createlang plpgsql widge4
move the packages directories that are unported to /web/widge4/tmp
restart the server.
fill up all the data required (administrator infor...)
when you get to the page that sais that you have installed OPACS4
succesfully shutdown the server
copy the clean DB to a new DB
createdb -T widge4 widge4-clean
move the unported package back again to the package directory, try loading now.
