I've done this a lot in the current Xcode, if anyone's interested I could give some help or show you some sample projects.

@cpenny42 sure I'd be interested!

Here's a few links to some basic externals that should work:

let me know if they don't work for some reason. Here's a good pdf that goes over more of the details: http://pdstatic.iem.at/externals-HOWTO/pd-externals-HOWTO.pdf
