build ejabberd mac osx 10.9.5

try to build ejabberd from source on mac osx 10.9.5.
after installing homebrew, autoconf, automaker, libtool, erlang, I still have an error when making.

configure: error: libyaml library was not found

brew install libyaml does not help. and manually download libyaml and make install does not help either. although it's indeed in /usr/local/include

After installing  xcode 6.1 and command line tools for osx 10.9 for xcode 6.1,
the issue is gone. ^_^

osx install brew autoconf automake

install brew and others in osx

install homebrew first

  ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"

  brew install autoconf

  brew install automake
