The relevant error in the log appears to be this problem when trying to build ircd:
:info:build /usr/bin/clang -o ircd blalloc.o bsd.o channel.o clientlist.o clones.o confparse.o fdlist.o fds.o hash.o hide.o inet_addr.o ircd.o klines.o list.o m_nick.o m_rwho.o m_server.o m_services.o m_stats.o m_who.o match.o memcount.o modules.o packet.o parse.o pcre.o probability.o res.o s_auth.o s_bsd.o s_conf.o s_debug.o s_err.o s_misc.o s_numeric.o s_serv.o s_user.o sbuf.o scache.o send.o struct.o support.o throttle.o userban.o whowas.o zlink.o ssl.o socketengine_poll.o rc4.o dh.o version.o -lz -L/opt/local/lib -lcrypto -lssl
:info:build Undefined symbols for architecture x86_64:
:info:build "_first_visible_channel", referenced from:
:info:build _m_who in m_who.o
:info:build ld: symbol(s) not found for architecture x86_64
:info:build clang: error: linker command failed with exit code 1 (use -v to see invocation)
The build system then doesn't notice this error and proceeds to the destroot phase as if nothing was wrong; the destroot then of course fails when it tries to install ircd because it isn't there since it wasn't built.
