Debian/ubuntu mozembed package

I have been trying to make php-gtk with mozembed work on a debian/ubuntu 
system to not avail.
It's not too hard to get the needed packages for php-gtk (which are 
still too much for my taste) but
I can't find which package contains mozembed. At least one which is 
recognised by the configure
script. It searches via pkg-config for either firefox-gtkmozembed >= 
1.5.0 or mozilla-gtkmozembed >= 1.7.0
Needless to say, there's no package with those names. Similar pakages 
like firefox-dev, mozilla-dev, libxul-dev
or libxul0d don't provide that. I even tried by installing some of the 
few packages refering to mozembed (there're
only bindings for other languages) in the hope they'd install what i needed.

It's not such an uncommon configuration nobody has tried it before, and 
there MUST be a way to get mozembed
other than building mozilla. But i'm unable to find it :(

Can anyone help me with this?
Thanks
