Error messages running autogen

[Rodolfo Medina <rodolfo.medina@gmail.com>]

I want to install libdvdread from source.  After unpacking the tarball, I cd
into the source dir and ran autogen but got the following:

 $ tar xjvf libdvdread-4.1.3.tar.bz2
 $ cd libdvdread-4.1.3
 $ ./autogen.sh --prefix=/usr
 autoreconf: Entering directory `.'
 autoreconf: configure.ac: not using Gettext
 autoreconf: running: aclocal
 autoreconf: configure.ac: tracing
 autoreconf: configure.ac: not using Libtool
 autoreconf: running: /usr/bin/autoconf
 configure.ac:98: error: possibly undefined macro: AC_LIBTOOL_DLOPEN
       If this token and others are legitimate, please use m4_pattern_allow.
       See the Autoconf documentation.
 configure.ac:99: error: possibly undefined macro: AC_DISABLE_STATIC
 configure.ac:100: error: possibly undefined macro: AC_PROG_LIBTOOL
 autoreconf: /usr/bin/autoconf failed with exit status: 1

I'm stuck here, and googling around didn't take a solution.  Any help very
appreciated.

Thanks
Rodolfo
