Replace openssl by libressl, view if libressl port from 6c37-dropin is updated with latest libressl upstream. First install libressl to ensure it gets all the sources;
$ sudo prt-get depinst libressl
After complaining about openssl files remove openssl;
$ sudo prt-get remove openssl
$ sudo prt-get depinst libressl
