don't build wiringPi
don't run dpkg-architecture
remove reference to AppMain.tcl

fix bugs that were keeping the dmg package from building (leaving out the license for now because it relies on outdated Carbon libs)

* add flag for compatibility with older OSX versions
* change library paths in script so that external dependencies are found
* build with jack support

remove pentium4 arch (I'm on a MacBook Air-- not sure if that would compile on some other Mac)
