[LAU] compiling jack-osc?

I'm trying to compile (or otherwise obtain) the jackd utilities found at http://rd.slavepianos.org/sw/rju/ , but I don't seem to be able to. In particular, I'm interested in using the jack-osc tool to convert jack transport messages (from Ardour) to osc messages. (Incidentally, if anyone knows of another way of doing this, please let me know.) Although the sources are there, I can't figure out how to compile them - in fact I don't even know if they're in a compileable state. I tried running make and playing around with gcc, but they seem to depend on some files that aren't present there. I'm running Arch Linux, but can't find a package for them in the AUR (Arch user repository). Are these tools still current, or have they succumbed to bit rot? Does anyone know how I might be able to compile them? Thanks, J
