I tried to emerge gentoo-sources-2.6.17-r4 but it failed complaining that "Manifest could not find file, gentoo-sources-2.6.17-r5 ebuild". I don't have the exact error with me anymore. After checking with the online package manager, I found out that that kind of ebuild hasn't been made yet so this might be a bug. I solved this by manually editing the /usr/portage/sys-kernel/gentoo-sources/Manifest file and commented the lines refering to gentoo-sources-2.6.17-r5 ebuilds.
It works for me, sorry. Have you tried syncing again ?
(In reply to comment #1) > It works for me, sorry. Have you tried syncing again ? No, I tried it yesterday evening and I don't usually sync twice a day or even everyday for that matter. I'll try to resync once I get from work to see if it's been fixed.
Just resynced and the problem seems to be fixed :)
