OSX 10.10:

INSTALL_NAME_TOOL(1)                                      INSTALL_NAME_TOOL(1)

       install_name_tool - change dynamic shared library install names

       install_name_tool  [-change  old  new  ]  ...  [-rpath  old  new  ] ...
       [-add_rpath new ] ... [-delete_rpath new ] ... [-id name] file

       Install_name_tool changes the dynamic shared library install names  and
       or  adds,  changes  or  deletes the rpaths recorded in a Mach-O binary.
       For this tool to work when the install names or rpaths are  larger  the
       binary  should  be  built  with  the ld(1) -headerpad_max_install_names
