Ken, your changes look a bit weird. You modified debian/patches/ubuntu_lpi.patch, added a new debian/patches/ubuntu_lpi2.patch, and disabled ubuntu_lpi.patch in series without adding ubuntu_lpi2.patch. You also removed autoconf.patch without documenting the reason in the changelog. Indeed LPI doesn't exist in the current PPA packages.
