During a build of curl with LibreSSL as SSL library the build fails due to detecting an unavailable function during configure. What I've noticed is that the order in which the libraries are searched differs between 10.0/clang3.3 and 10.1/clang3.4 Attaching config.log for both versions. If you wish to test this, add WITH_OPENSSL_PORT= yes OPENSSL_PORT= security/libressl to your make.conf and build ftp/curl
