well...there are two ways. The first is to see if it works, while out of date. You do this by clicking the "Load Out-of-Date Addons" box at the top of the addon screen.
The second way is to find a newer version of Bongos. I'm not sure which UI sites I'm allowed to link, so I would just suggest googling for it. Most sites have an intermediate screen describing the addon before you download it. Check to see if it's out of date or not.
Here...I found it on this site.
