Have you enabled GSSAPIAuthentication (and maybe GSSAPIDelegateCredentals and PreferredAuthentications) in the client? The former two default to "no" and the latter's default does not have "gssapi-with-mic".

Thanks, Darren. Do you know if there is any reason why ssh_config does not list (commented out) all of the defaults in order to give the installer a list of toggleable items? (like sshd_config already has, extensively)

That solved the problem though.
