ssh -o kexalgorithms=diffie-hellman-group14-sha1
works

Perhaps its a compatibility issue with LibreSSL 3.0.0
The production ssh release does work with LibreSSL 3.0.0 however.
I compile LibreSSL 3.0.0 separately and install into /usr/local -- that
is the reason for the with-SSL I configure.

macOS seems to come with LibreSSL 2.7.3 out of the box.
