Comment:

 all these old ports build with openssl 1.0 -- it's getting them to openssl
 1.1.1 that is giving us trouble.

 Homebrew just lists it as 'incompatible' with openssl 1.1.1, and browsing
 the web is not useful.

 I have a partial patch for the first bit of the fix cooked up. The next
 bit, the `HMAC_CTX` part, is not done yet. Info here on how to fix that
 <https://www.openssl.org/docs/man1.1.0/man3/HMAC.html>

 Here's my partial patch for the first bits (incomplete).
