[Libreoffice] Newbie dev question: no "rawbuild" directory after git clone

Hello folks,

I'm attempting to get a proper development environment to build 
LibreOffice.  Pulled a clone of the git repository, and it looks like I 
have everything except for the loroot/rawbuild directory.  Problem:  
looks like the rawbuild directory is needed for building LibreOffice.  
Here's what I did.

# apt-get build-dep openoffice.org
# exit
$ git clone git://anongit.freedesktop.org/git/libreoffice/build loroot
$ cd loroot
$ ./autogen.sh --with-git --with-num-cpus=4
$./download

After that, an "ls " shows everything on the development Wiki page 
except for rawbuild/.

The dev box is a Debian Lenny machine with all updates, and I will also 
eventually do this on a considerably more powerful box running CentOS 5.

Anything I'm missing here?

Thanks,

--TP
