A recent upgrade from nettle-2.7.1-r4 to nettle-3.1.1 broke all packages that depend on libarchive, most notably cmake (nettle <- libarchive <- cmake). This breakage would have only occurred for users of package managers that don't have an equivalent of preserved-libs; I use paludis). This upgrade bumped the SO version of nettle from 4 to 6, which made the dynamic loader refuse to load libnettle. Changing libarchive's dependency on nettle to "dev-libs/nettle:0=" would be sufficient to prevent future breakage, since it will force a rebuild of libarchive.

Sorry about that, fixed the bug, forgot to close it out. Should be fixed in >=3.1.2-r5
