After a long break, I have updated my repository with aoTuV beta 5.5 tuning. There you can find the patched libvorbis for Gutsy (7.10), Hardy (8.04), and Intrepid (8.10).
To use it all you must do is add a line like this in your /etc/apt/sources.list file:
deb http://ppa.launchpad.net/pjssilva/ubuntu intrepid main
After that you can use update-manager to download the patched library.
To get the patched sources add
deb-src http://ppa.launchpad.net/pjssilva/ubuntu intrepid main
If you have any problems with this packages, please let me know.
