dhcpcd, not dhcpd. Yes, dhcpcd can do DHCPv6 and DHCPv6-PD.

With most ISPs to get a global address on the PPP interface itself you
just need to do SLAAC ("inet6 autoconf" in hostname.XX).
Delegation for "downstream" interfaces is a bit harder to configure.
That's no worse than v4 though - the method normally used for this
with v4 (setting it by hand) works on v6 of course if the ISP permits
- but there's the extra option of using PD (possible but uncommon for
v4; widely used for v6).
