Perl Monks uses a modified version of 0.80, which isn't really compatible with the 1.0 snapshots. I think the ElistAndModerate nodeball came from Perl Monks and I know it used to work with 0.90. I wouldn't recommend installing or using Everything 0.80 because there's no documentation and I don't know anyone who really remembers what it's like.

If you have time, I think your best option is to post what breaks in ElistAndModerate to the everydevel-opers list so that people there can help you debug it.
