@@GLIBCXX_3.4.14 symbols are in gcc45/libstdc++.so. Try to add -lstdc++
or use CXX otherwise it picks up libstdc++.so from /usr/lib.

Another way is to adjust search path a little, place $LOCALBASE/lib/gcc45 before /usr/lib

  # sed -i '' "\|_LDC.*/usr/lib|s|\"|\"${LOCALBASE-/usr/local}/lib/gcc45 |" /etc/rc.d/ldconfig
  # /etc/rc.d/ldconfig restart
