I still have the one that worked on my server.. It could be that the RPMs are not in those locations any more. You can always manually download the rpms listed in the script and just follow the steps the script lays out manualy.
I have seen mention of a contrib or howto for 4.3.9 but haven't gone looking for it.
I'm in the chat room if you want to give me your email so I can send you a copy of the script I used.
