how to build pulseaudio from sources in karmic

I am trying to get jackd and pulseaudio to work together nicely. For that it appears I need the module-jack-sink.so
see http://ubuntuforums.org/showthread.php?t=1163390

But I get errors when running the following two commands. Any suggestions on how I can either get the pulseaudio modules for jackd or get the dependencies and sources "working" on karmic(9.10)?

# apt-get build-dep pulseaudio
# apt-get source pulseaudio

But I get the following errors when using the above commands

$ sudo apt-get build-dep pulseaudio
