libtool & aclocal.m4 problems (4.3)

I am tracking down a warning when running phpize: catnip 09:44:27 bfrance> phpize You should update your `aclocal.m4' by running aclocal. Configuring for: PHP Api Version: 20020918 Zend Module Api No: 20020429 Zend Extension Api No: 20021010 phpize is running "libtoolize -f -c" which does: egrep '^AC_DEFUN\(A[MC]_PROG_LIBTOOL' aclocal.m4 The problem is aclocal.m4 doesn't have a line like this: AC_DEFUN\(A[MC]_PROG_LIBTOO it does have a line that would match this (added the \[), but that would mean changing libtool: AC_DEFUN\(\[A[MC]_PROG_LIBTOO The problem is I don't know enough about aclocal.m4 to know if just removing the []'s around "AC_DEFUN([AC_PROG_LIBTOOL]," (Line 1831) will break other things. Or is there another way to fix it? libtool-1.4.2 FreeBSD 4.x Thanks, Brian
