***** PDP and its deps  : http://zwizwa.fartit.com/pd/pdp/
***** imlib2 		: http://sourceforge.net/project/showfiles.php?group_id=2
***** theora 		: http://www.theora.org/files/

OPTIONALLY ::
=============
***** ffmpeg		: http://ffmpeg.sourceforge.net/cvs 
( --with-ffmpeg=PATH )    ----> 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 )
( --with-mpeg4ip=PATH )    

b/ ./configure --with-pd=PATH --with-pdp=PATH [--with-ffmpeg=PATH] OR [--with-mpeg4ip=PATH] ( not both )

c/ make clean 

d/ make

e/ as root, make install

f/ 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.
