Comment (by ryandesign@…):

 That's why I waited until gnutls was version-3-compatible before updating
 nettle.

 The only port that depends on nettle that I did not revbump, and whose
 version 3 compatibility I did not test, is pike, because pike is years
 outdated and does not build or work anyway. I will try updating pike to a
 new version.

 If you are aware of any ports other than pike that are negatively impacted
 by this nettle 3 update, please let me know.
