it seems that the ftp site, xanim.va.pubnix.com is now password protected (if someone could please confirm this), so that emerge kde-multimedia is unable to conclude successfully.
of course, that would be for the latest kde ebuilds :)
This is an xanim issue not a kde one. Please reassign as appropriate.
I this still an issue? I see that xanim's ebuild uses the gentoo mirrors for pulling the tarballs.
