[Samba] Installing Samba4

[Montervino, Mariano]

We have trouble installing samba4 and we can´t found documentation about
setup, join domains, etc...

We use rsync command to download samba
rsync -avz samba.org::ftp/unpacked/samba4 .
and when run ./autogen.sh to generate configure files return the following
error:
./autogen.sh: running script7mkversion.sh
./script/mkversion.sh: version.h created for
Samba("4.0.0tp3-svn-build-UNKNOWN)
./autogen.sh: running autoheader
configure.ac:108: error: m4defn: undefined macro: _AC_SUBST_VARS
configure.ac:108: the top level
autoheader: autom4te failed with exit status: 1
at /usr/local/bin/autoheader line 163
