According to your logs, you're using a 0.7.x version of ipsec-tools,
which should still use the "old" PFKey interface also used by NetBSD
(any version actually).

So I fear you found another issue which just looks like the known
PFKey issue !

Just to be sure: does the same exact configuration work with older
versions of NetBSD and/or ipsec-tools ?

Not afaik: such changes actually happened only in FreeBSD 8.0+ and
ipsec-tools HEAD (which will become 0.8 branch).
