Hi again, the current quota tools in portage tree is release 3.04, the changelog of www.sf.net/linuxquota/ looks good enough to let the portage tree enhanced by this new release. Since I just can't do it my self, I'd be happy if someone else would put a new copy of the ebuild 3.06. Best regards, Christian Parpart.
Alright, committed and masked for testing. Thanks!
