I'm running Debian Sarge with a 2.4 kernel, and this libdsp which 
jack_convolve depends on is a real problem. libdsp needs nptl threading 
style, and that seems to require linux 2.6. I don't know if Debian 
supports nptl either.. I just can't compile libdsp.

I'm not going to switch to 2.6 now. I don't have enough time.

I tried removing the "DEFS += -DUSE_NPTL" line from the 
libdsp/DynThreads/Makefile, but it ends up complaining about a Mutex.hh 
file which does not seem to exists anywhere in the Debian distribution.

Before all of that, I tried to use the libdsp0 and libdsp-dev Debian 
packages, but these are both from the 3.3.6 libdsp release, which 
jack_convolve does not seem to recognize.
