Preferably do a 'make distclean', apply the patch and then try to rebuild using exactly the configure call that produced the crash before (i.e. without -gung-ho). yes, makeinfo is part of GNU texinfo. Get it from you nearest GNU mirror. maybe, but I doubt it. running in place should be fine. Have you installed the necessary packages (or the sumo tarball)?
