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

Question

Hello everyone

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 terminal it reports

Last login: Sun Jun 13 07:22:07 on ttys002
  unknown required load command 0x80000022
Trace/BPT trap
logout

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
