What I'm wondering is, that xz shall give the same error when executed directly in terminal. This shouldn't happen, because xz and liblzma.so belong to the same package, and I don't get this error. There's, btw., no liblzma.so.0 in the package xz. So first try to update your system (pacman -Syu) from another mirror as Meyithi suggested. If this doesn't solve the problem, try to reinstall xz and yaourt. Don't forget to remove the old xz package from the pacman cache (/var/cache/pacman/pkg) before, so that it's not just reinstalled but downloaded from the mirror again. Heiko
