Hi

Seems you have compiled pd without jack support. You need the libjack-dev
library installed and watch out for the information that ./configure gives
you.

You also have the option of backporting packages from Debian unstable:
just add

deb-src ftp://ftp.de.debian.org/debian unstable main

to your /etc/apt/sources.list

then do (as root)

apt-get update
apt-get build-dep
apt-get source --compile puredata

This leaves you with a debian package puredata_xxx_i386.deb, which
you can install with dpkg -i puredata_xxx_i86.deb
