How to use the delocate.tools.get_install_names function in delocate

def repath_lib(lib_fname, old_path, new_path):
    install_id = get_install_id(lib_fname)
    L = len(old_path)
    if install_id and install_id.startswith(old_path):

        if name.startswith(old_path):
            set_install_name(lib_fname, name, new_path + name[L:])
