a/ first, install  :

MANDATORY ::
============
***** PD sources 	: http://www-crca.ucsd.edu/~msp/software.html
***** PDP and its deps  : http://zwizwa.fartit.com/pd/pdp/
***** imlib2 		: http://sourceforge.net/project/showfiles.php?group_id=2
***** Image Magick 	: http://www.imagemagick.org
                          ---->  watchout !! configure with --enable-shared 

OPTIONALLY ::
=============
***** ffmpeg		: http://ffmpeg.sourceforge.net/cvs 
( --enable-ffmpeg )       ----> watchout, it requires the cvs snapshot !
                          + don't forget to activate mp3 and vorbis support in ffmpeg : 
                          ./configure --enable-mp3lame --enable-vorbis
OR

***** mpeg4ip		: http://mpeg4ip.sourceforge.net/ ( download mpeg4ip v1.0 )
( --enable-mpeg4ip )    

b/ fix PD, PDP and FFMPEG/MPEG4IP paths in configure.ac

c/ autoconf 

d/ ./configure [--enable-ffmpeg] OR [--enable-mpeg4ip] ( not both )

e/ make clean 

f/ make

g/ as root, make install

h/ modify your pd start-up script :

pidip is a library, it should be loaded
with the "-lib <path>/pidip" command line option
but, BEWARE, it should be place AFTER the 
loading of PDP library ( option "-lib <path>/pdp" )

Enjoy!!

Thanx for getting here.
