Seems you don't have app-arch/xz-utils installed. Please do emerge --sync (you should be installing mpfr-2.4.1_p5 as it's current stable) and update portage and system set. If xz-utils are not merged before mpfr, you can always do emerge -1 xz-utils I can see that you're trying to update quite outdated system. You may expect it won't be a piece of cake. I would recommend you visit #gentoo @ irc.freenode.net. People there may help you with such errors immediately. Please close this bug if this solves your problem. Best regards, Kacper Kowalik
Please update your system target.
