Is ther anyone familiar with Erica Sadun's APIKit(app private api scanner)?

I'm trying to use APIKit to scan my codes to detect if there is private API. apiscanner should run as

./apiscanner ~/Desktop/MyPath/myapp.app 

I used command 'cd' go to the directory where apiscanner is. But if I call ./apiscanner ~/Desktop/MyPath/MyApp.app on termina开发者_C百科l it reports

Even if I copy the files apiscanner and doit to MyPath, then execute, I get the same problem. I think there is something wrong when I run apiscanner under Mac OS X.

Welcome any comment

Thanks

This is what happens when 10.6 only binaries are run on an older system (10.5 or earlier).
