Successful build on OSX Snow Leopard.

Requires:
* macports
* library dependencies listed on
  http://idjc.sourceforge.net/install_build.html
* JackOSX http://www.jackosx.com/
* Xquartz

IMPORTANT: it builds, it starts, but it fails to connect to Jack Server.
Also, starting the mixer it sucks the whole cpu resources. ALPHA BUILD
IS ALPHA, try it at your own risk.
