OpenSSL 1.1 intruduces a new API. Not all ports are compatible with the new API.
Since FreeBSD intends to update OpenSSL in base to 1.1.x these ports should be either fixed or removed.
The intent to update OpenSSL to 1.1 in 12 has now officially been documented in Bug #228912
For reference the exp-run for OpenSSL 1.1.1 in base is now in progress in PR 231931, http://package18.nyi.freebsd.org/build.html?mastername=headamd64PR231931-default&build=2018-10-04_07h49m12s
