I had similar problems, and I have solved them adding a couple of symbolic links (unfortunately, I don't remember exactly which ones).
I suppose you installed newer versions of autoconf and automake, while you did not update libtool itself. The newer auto* look for macros in a different directory. You may fix the problem using --include options or symlinking the macros.
One more option is to symlink
ln -s /usr/share/autoconf/autoconf/autoconf.m4 /usr/local/share/ autoconf/autoconf/autoconf.m4
(assuming you installed autoconf in /usr/local/bin); additional symlinks may be required. Probably adding the
--include /usr/share/autoconf/autoconf/
should be tried first since it is not a 'modification'. Options -ivf for autoreconf may also be useful.
