This kind of subslot mess is so irritating:
workstation ~ # emerge -aDjtuv --changed-use @world && dispatch-conf && emerge
-a --depclean && revdep-rebuild -i && clear && exit
These are the packages that would be merged, in reverse order:

Just whomever decided to add the 16 subslot caused libpng ~amd64 to be pulled
for those amd64 packages. Gentoo has a long history of libpng ~amd64 problems.
What is the need for the stinking 0/16 subslot here? What was it not good
enough to slot 1.6.6 as 1.6?
And with this *new* subslotting, what is The Gentoo Way (TM) to keep stable
libpng in this instance?
Cheers,
Bruce
