Symbols references are enforced at launch time, except for the ones marked as weak import.
What version of Xcode are you using? What compiler and SDK are you using? What is your project's Deployment Target setting?
The symbols for block objects should have been marked as weak import if you are using a sufficiently new OS X SDK and your Deployment Target is set correctly. Then your app would have been able to launch and run as long as it did not actually use block objects on 10.5.8.
