The stage3 for armv6j-hardfp is no longer available on the mirrors. Most recent was stage3-armv6j_hardfp-20120628.tar.bz2 which is now gone. The above link returns a 403 error code on distfiles.g.o http://distfiles.gentoo.org/releases/arm/autobuilds/latest-stage3-armv6j_hardfp.txt still says that stage3-armv6j_hardfp-20120628.tar.bz2 is current.
I've pushed the stages again...not sure how did that happen...i'll keep this open until they're on the mirrors again
Should be fixed
