The KDE 3.0 ebuilds do not seem to be using the mirrors defined in kde.org.eclass The emerge process will try ibiblio then the first mirror listed in kde.org.eclass and then fail ... some of the kde ebuild packages also do not seem to contain the directive to enherit this eclass file...
Dan, can you tell me whether this is a problem with the eclasses or a Portage problem? It could be a Portage problem.
Definitely a portage problem. I put all the mirrors in SRC_URI. All the mirrors show up in my cache file, too, so I know they are getting there.
