"missing its dependency information"

I'm trying to use refactoring to rename an ivar in the Moriarity 
example, and I get this message:

    File "MoriarityController.m" is missing its
    dependency information and can't be
    analyzed for sake of file
    "MoriarityController.h".

    Rebuild a target containing the file and try again.

I've tried doing a Clean All and rebuilding.  I've tried deleting the 
build directory and rebuilding.  I've tried rebuilding the Code Sense 
index.  Nothing changes.  Anybody know what the fix is?  I didn't find 
anything in Google or CocoaBuilder.
