Do you know jack?

Yesterday I committed a port of JACK, the Jack audio connection kit. It is a low-latency audio server, used by several Linux Audio applications. Unfortunately it is based on ALSA so it was not available on FreeBSD for a long time. But now it has an output driver for portaudio, which is available on FreeBSD. After some bug fixinig i think it should work now. Unfortunatly I was not able to test much, because of university. There is still a lot to do:
* The port does not install its documentation
* It probably does not work on FreeBSD alpha 4.x
* The Jack-OSS driver does not work yet
* Other ports that support jack need a dependency on jack
