This project is not currently actively maintained, as the original author lost his enthusiasm about Max OS X, and because his Apple hardware died.
The code is not up-to-date with the latest releases of XCode, and might not even be compatible with new rules declared by more recent version of OS X.
Hence, if anyone is interested to move this forward and he/she is looking for a new project to maintain, please drop me a line. I'll happily hand over the maintainership.
