Why is Avant window navigator not available in ubuntu 12.10?

http://askubuntu.com – Installing the ubuntu 11.10 packages works.I can't compile awn on ubuntu 12.10. And i can't install it with the software-center but the program is listed on it. It isn't like awn depends to 100 % on vala, so all non vala written parts of awn schould be runnable on ubuntu 12.10 too. (HowTos)
