No, I intended you to to read it instead of blindly executing it.
The missing modules are all Mac OS X components, which I use for
displaying an alert and doing IPC with my application.  Here's a
minimal version (untested).

    (stdout, stderr) = tlmgr.communicate()
    
    output = "".join([c for c in stdout])
    is_list_line = False
    count = 0
    actual_location = None
    for line in output.split("\n"):

            is_list_line = True
        elif line == "end-of-updates":
            is_list_line = False
        elif is_list_line:
            comps = line.split()
            #
            # d = deleted on server
            # u = updated on server
            # a = added on server
            # f = forcibly removed
            # r = reverse update
            #
            
            # ignore anything that's not an update or addition
            if len(comps) >= 2 and comps[1] in ("a", "u"):
                count += 1
        elif line.startswith("location-url"):
            actual_location = line.strip().split()[-1]
    
    return count, actual_location

if __name__ == '__main__':
    
    count, actual_location = check_for_updates()
