This error usually means your install_name_tool
command is too old for your operating system. You appear to be on Mountain Lion, which means you must be running Xcode 4.4 or later. If not, upgrade Xcode, which you can do from the Mac App Store or Apple Developer Connection web site. In these versions of Xcode, command line tools must be installed separately, from within the Xcode application, in the Preferences window, in the Downloads section. Please go there and ensure the command line tools are installed and up to date.
