I guess the error message means SSH protocol version 2 server keys are missing
on the remote system. The in-tree ssh client tries protocol 2 first.
(At least NetBSD's ssh server and client use different key sets for SSH protocol
version 1 and 2.)

For NetBSD system I suggest updating /etc/rc.d/sshd and then stopping and
starting sshd (with that script). That should automatigically create missing
key pairs.

For systems you don't control you can put something like

Host some.other.host
	Protocol 1,2

in your ~/.ssh/config to force it to try protocol version 1 first and then 2 for
that specific host.

And if you want public key authentification to work with protocol 2, please
read the section "SSH Protocol Version 2" in the ssh manpage and
ssh-keygen's manpage. :-)
