Both 10.7 and 11.2 fail on FreeBSD 12-STABLE if --with-openssl is part of the configure string.
The issue appears to be that FreeBSD updated OpenSSL to OpenSSL 1.1.1a-freebsd 20 Nov 2018 where the 11.x release of FreeBSD (and previous was on 1.0.x -- e.g. OpenSSL 1.0.2o-freebsd 27 Mar 2018)
The errors start here:

Has anyone looked into and dealt with this yet or have suggestions?
