Hey Steve,
From what you posted, it seems like the problem is that he's not correctly referencing the libTurboActivate.dylib file:
dyld: Library not loaded: @rpath/libTurboActivate.dylib...Reason: image not found
If he's making a C, C++, or Objectiv-C Mac OS X app then he should check out the "Using TurboActivate on Mac OS X" article. It specifically talks about the "runpath" and finding the libTurboActivate.dylib file at runtime. He should start with a simple console C app to see how it's done.
If he's using another language then he should make sure he's properly loading the dylib at runtime.
Maybe we need i386 only without ppc support would help also he thinks.
The dylib is a universal binary -- it already has i386 and x64 binaries built in. The PPC version is never loaded when you're on an Intel CPU. That being said he can always remove the "PPC" portion of the library (again, described in "Using TurboActivate on Mac OS X"), but this won't solve his problem. The problem is the dylib is not being found.
Lastly he should be using Mac OS X 10.5 or above. Older versions won't work.
