I believe the symptoms you describe come from mixing autoconf versions,
e.g. running autoconf 2.13 on a configure script that uses 2.5x or
vice-versa. [The problem is probably that "aclocal.m4" was created
with the other version of autoconf.]
You can usually recover by re-running aclocal & then autoconf.
But you have to get the versions right. As Ben said, you can
force autoconf2.50 by putting AC_PREREQ(2.50) in configure.in.
