Debians NM installs the gtk-doc with the packages libnm-glib-dev ( see http://git.debian.org/?p=pkg-utopia/network-manager.git;a=blob;f=debian/libnm-glib-dev.install;hb=HEAD ) and libnm-util-dev ( see http://git.debian.org/?p=pkg-utopia/network-manager.git;a=blob;f=debian/libnm-util-dev.install;hb=HEAD ). I think ubuntu should do the same.
