Compile it with JACK and without portaudio support:
./compile_linux_fftw_jack.sh

Note: the build-script compiles *.cpp - yet no function from
PAaudiooutput.cpp is used in the JACK version. Either fix the
build-script or simply   mv PAaudiooutput.cpp PAaudiooutput.outoftheway

AFAIK Paul Nasca does still develop and maintain it.
