The following instructions work for me on OS X 10.9 after patching a few packages. This builds, but I haven't tested running it. avahi seems to be a Linux-only thing, so we won't install related packages. I guess you don't need them for you purpose.
Edit: forgot one patch.
mkdir turtlebot_ws
cd turlebot_ws
. /opt/ros/hydro/setup.bash
# download source, but exclude zeroconf_avahi since this seems to be linux only thing
rosinstall_generator turtlebot_gazebo --rosdistro hydro --deps --wet-only --tar --exclude RPP zeroconf_avahi > turtlebot.list
wstool init -j8 src turtlebot.list
# manually install dependencies (rosdep rules are not complete on osx)
brew install libftdi0 libusb-compat
# the following is a dependency, but not needed for compiling. So you might need them to execute, or you might not.
brew install redis
# check what rosdep has to say
rosdep check --from-path src -i --skip-keys "avahi-utils ftdi-eeprom libftdi-dev avahi-daemon libusb-dev redis-server"
# this should only tell you to install "gcc" and "ros/hydro/zeroconf_avahi_suite", ignore those.
# Install any additional packages coming up here by hand.
