The ebuild doesn't have amd64 keyword. See comment below: http://bugs.gentoo.org/show_bug.cgi?id=131527#c639 Forcing ~x86 to be accepted on an amd64 machine seems to work just fine. :-) Reproducible: Always
Indeed, amd64 should work fine but I don't have any amd64 hardware. Reassigning the bug to amd64.
Tested and passed here so keywording.
