net-fs/nfs-utils provides three systemd unit files (nfsd.service, rpc-mountd.service, rpc-statd.service) and all of them depend on rpcbind.service. But this unit file does not exist (or at least is not provided by net-fs/nfs-utils) so none of the services can be started.

I guess you need to: emerge -1 =net-nds/rpcbind-0.2.0-r1 You'll need to unmask proper keyword, but since your using unstable nfs-utils you already know how to do that.
You are right, I didn't notice that. Maybe >=net-fs/nfs-utils-1.2.7-r1 should depend on >=net-nds/rpcbind-0.2.0-r1 then and not just net-nds/rpcbind.
+ 07 Aug 2013; Kacper Kowalik <xarthisius@gentoo.org> nfs-utils-1.2.7-r1.ebuild, + nfs-utils-1.2.8-r1.ebuild: + Adjust dependency on rpcbind so that version with systemd units is pulled in + for packages that require it. Fixes #480006 by redneb <redneb@gmx.com>
