Having that header is not going to help.  The header declarations a function in libSystem.dylib which the unwinder calls to get the address of the __eh_frame for a given pc.  That function is not in the darwin8 libSystem.  We'll need to write an equivalent using dladdr() and getsectiondata() for older MacOSX versions.
