autoconf error

[A. Artu YILDIRIM]

Hi, to examine the codes of dbus project, I fetched all source tree and
after I invoke autoconf tool, it gave me the error seen below:

****************
configure.in:12: error: possibly undefined macro: AC_LIBTOOL_WIN32_DLL
      If this token and others are legitimate, please use
m4_pattern_allow.
      See the Autoconf documentation.
configure.in:13: error: possibly undefined macro: AC_LIBTOOL_RC
configure.in:17: error: possibly undefined macro: AM_INIT_AUTOMAKE
configure.in:18: error: possibly undefined macro: AM_CONFIG_HEADER

configure.in:119: error: possibly undefined macro: AM_CONDITIONAL
configure.in:1394: error: possibly undefined macro: AS_AC_EXPAND

What to do? Thanks all,
