[Comment 7 Samuel Holland 2017-05-10 22:55:08 UTC]

This looks to actually be a bug in skalibs, as byte_copy is not used anywhere in s6-dns. It's only referenced from https://github.com/skarnet/skalibs/blob/4fd66d857b5e0c9cea39b48fde1b3c5e50ee687e/src/headers/ip46-without ...which gets installed as part of ip46.h only if you have ipv6 disabled. byte_copy is a macro from another header in skalibs, so there's a missing include somewhere.

This is fixed in >=dev-libs/skalibs-2.5.0.1
