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.
