how can i use libgpod.4.0.0 from Jaunty?

I have the following problem: https://bugs.launchpad.net/ubuntu/+source/libgpod/+bug/461639 while using rhythmbox with ubuntu 9.10 and while using a 4th generation black iPod nano. One of the responses to the problem was this: An update: this bug is specific to the 8GB black nano iPod with last 3 digits of the serial number "3R0" (the last character is the number zero). libgpod.4.1.0 is looking for "3RO" (the character "O") when trying to identify the model number.

A workaround is to use libgpod.4.0.0 from Jaunty. My qestion is, how can i use "libgpod.4.0.0 from Jaunty"?
