Compilation failed while executing : ld64

I'm getting this error while packaging my application for iOS:

Error occurred while packaging the application: Compilation failed while executing : ld64

The application compiles and runs fine on my coworker's machine, but consistently does this on mine.  The research I've done on this suggests this has to do with ANE's.  I'm using 3- two require IOS Version 5.0, the third doesn't seem to specify anything.

Is there anything I can do to get a more descriptive failure?

Thanks, I've spent way too many hours trying to get past this.
