xorg-x11-7.0-r1 marked ppc. The dependencies that aren't marked ~ppc are either not available for the platform(-ppc), or are marked ~ppc64. All of those cause me to wonder how the ebuild was marked ppc.
Repoman shows no problem, what is the issue here? Are you having problems?
David was trying to use vesa on ppc which won't work. Closing as invalid.
