[chuck] Bus Error - Trying to run ChucK for the first time

[Gary P.Scavone]

Hi Ge,

If ChucK still relies on RtAudio for its audio I/O support, then there 
is no Jack support for OS-X.  I honestly don't know why someone would 
want to use Jack in OS-X, since it is built on top of CoreAudio 
(RtAudio supports CoreAudio directly).  And also note that RtAudio 
supports ASIO on Windows.
