It sounds then like this is a case of an "orphaned port", or one that has changed significantly enough that it certainly can no longer really be called the same Ingres port we've seen from Berkeley. I still think it should be a "port", however, it just means that the original tarball will have to live in our LOCAL_PORTS. To get a working RDB back in ports/databases, I think this would be worth the price.
