peculiar make error for 'na'

[Michael]

in my Module.xs file there is the declaration
    CODE:
        printf("# destroying %s\n", SvPV(ST(0),na) );
        safefree( (char*)self );

I get this error???? any clues would be appreciated

`na' undeclared (first use in this function)

This should be defined in the headers

#include "perl.h"
#include "XSUB.h"
