Unfortunately I can't get ivtools to build until ace gets updated to new upstream version (see #317488). I've fixed the most of the open bugs so far. Some of the changes done so far: * ivtools-dev has been renamed to libiv0-dev * ivtools-interviews and ivtools-unidraw have been merged into package libiv0 * soname has been set on built libraries * files are installed under /usr instead of /usr/X11R6
