Here is a repository i use on my gutsy install which always contains the latest builds of Pidgin and Rhythmbox. So no more hunting for debs or compiling sources 
Steps to add the repository:
1. Open Terminal (Applications->Accessories->Terminal)
2. Type “gksu gedit /etc/apt/sources.list”
3. Go to the end of the file and add the following onto a new line:
## Latest Pidgin/Rhythmbox
deb http://www.telemail.fi/mlind/ubuntu gutsy main
4. Save the file and close Gedit.
5. Add the public key so that apt does not complain about any authentication errors (type into terminal):
wget http://www.telemail.fi/mlind/ubuntu/937215FF.gpg -O- | sudo apt-key add -
6. Update your system (type in terminal)
sudo apt-get update && sudo apt-get dist-upgrade
7. Voila! You should now have the latest Pidgin and Rhythmbox!
Thanks for the repo link…
You are welcome Manas!
nice but its not official link, why the ubuntu guys are so slow:|, like our Govt Babus:D
Yeah.. Its not from Ubuntu. Ubuntu has a frequent release cycle (6 months) so they focus more on security updates rather than feature updates. That’s where these unofficial repos come in handy!
Cool , always needed this. I had asked you also a few times ;P
My pleasure
Thx Lads.
