where to get libxul-embedding for ubuntu 9.10 (karmic)

Hi all, I am trying to build mozembed project on ubuntu 9.10 linux
AMD-64 and I got all the necessary packages - i am getting this :
checking pkg-config is at least version 0.9.0... yes
checking for GTK... yes
checking for LIBXUL_EMBEDDING... no
configure: error: libxul-embedding is required


sudo add-apt-repository ppa:ubuntu-mozilla-daily/ppa
sudo apt-get install xulrunner-2.0-gnome-support
sudo apt-get install xulrunner-2.0
sudo apt-get install xulrunner-2.0-mozjs
sudo apt-get install libxul-dev


The libxul-dev package is installed along with these :
xulrunner-2.0-gnome-support,  xulrunner-2.0, xulrunner-2.0-mozjs,
libxul-dev

Any clue where to get this package called libxul-embedding ?

Thanks a lot in advance
