I think I see part of the issue.
1) I had a bug with the XCode script, that accidentally flattened out the Syphon.framework and resolved aliases (a bad flag)
2) Make sure you compile libJSyphon.dylib as release, so you get a universal library
3) I need to follow my own advice and remove PPC architectures from libJSyphon XCode build process.
Im in the process of updating SVN to fix these issues. Now that the build is semi-worked out, I do think its loading the dylib. Im not quite sure where to go from here, but i’ve found a few threads regarding this on Apples dev site (one specifically mentioning processing). Need to do some more debugging.
