dear list, i noticed that on Lenny (debian unstable), Pd-extended could not get installed unless you find libmpeg1 somewhere (which i found difficult to get).
there sould be other solutions but for the moment i found that installing: http://debian.mirror.inra.fr/debian/pool/main/libm/libmpeg1/libmpeg1_1.3.1-2... would solve the problems...
so in eight steps :
- add to /etc/apt/sources.list
deb http://www.debian-multimedia.org lenny main 2) update repo sudo apt-get update 3) install debian-multimedia sudo apt-get install debian-multimedia-keyring 4) download pd-extended wget http://downloads.sourceforge.net/pure-data/Pd-0.40.3-extended-debian-testing... 5) install it sudo dpkg -i http://downloads.sourceforge.net/pure-data/Pd-0.40.3-extended-debian-testing... 5bis) ignore dependencies errors 6) install missing depencies sudo apt-get -f install 7) get the missing one wget http://debian.mirror.inra.fr/debian/pool/main/libm/libmpeg1/libmpeg1_1.3.1-2... 8) install it sudo dpkg -i libmpeg1_1.3.1-2.1_i386.deb
et voilà...
best regards, vincent
