I've uploaded a version of the aolserver ebuild for the official 4.0 release and fixed the tDOM ebuild (DNS stopped resolving tdom.org so now it downloads from www.tdom.org).
The official Gentoo maintainer assigned to these (and the tcl) ebuilds says he doesn't have enough time to keep them up to date in cvs and is currently looking for someone else to take them on... once that happens they should appear in the main portage tree.
I would be interested in being a gentoo package maintainer, but I am not sure how to become one (I have mentioned it loosely to a few ppl in the past). I have submitted like 6+ or so packages over time to gentoo...
I think it would be great to get in the official cvs of gentoo with aolserver + modules and even openacs if possible. That was the whole point of making packages to me.
