configure errors

Okay.  When I run buildconf for phpgtk 0.1 I get this:

[root@studio2 php-gtk-0.1]# ./buildconf
aclocal: macro `AC_ADD_LIBPATH' defined in acinclude.m4 but never used
aclocal: macro `AC_ADD_LIBRARY_WITH_PATH' defined in acinclude.m4 but
never used
aclocal: macro `AC_ADD_LIBRARY' defined in acinclude.m4 but never used
aclocal: macro `AC_ADD_INCLUDE' defined in acinclude.m4 but never used
autoconf: Undefined macros:

You should update your `aclocal.m4' by running aclocal.

and when i run ./configure --prefix=/usr/local i get this:

Anyone know why this is? The same error has kept me from being able to
build the php cvs source.  I'm running redhat 7.1 with autoconf 1.3. Thans
in advanced.
