O Monks, please hear my question.

This concerns the distribution Audio::TagLib and the xs files therein, which interface to the C++ taglib library.

In one of the .xs files, some of the functions that are declared suffer from the (infamous?) error: 

Can't locate object method "header" via package "Audio::TagLib::Tag"

Here's a snip of the .xs file. isEmpty() is recognized, header() and the functions that follow it in the file are not. 

bool 
TagLib::ID3v2::Tag::isEmpty()
CODE:
    RETVAL = THIS->isEmpty();
OUTPUT:
    RETVAL

void 
TagLib::ID3v2::Tag::header()
PREINIT:
    TagLib::ID3v2::Header * h;
PPCODE:
    h = THIS->header();
    ST(0) = sv_newmortal();
    sv_setref_pv(ST(0), "Audio::TagLib::ID3v2::Header", (void *)h);
    SvREADONLY_on(SvRV(ST(0)));
    XSRETURN(1);

Applying nm(1) to the .so file suggests that header() should be located.

t _ZL35XS_Audio__TagLib__ID3v2__Tag_headerP11interpreterP2cv

Everything in this particular .xs that follows isEmpty() suffers the same fate. However, in the .c file compiled from the .xs files (there are quite a few), other functions from other .xs files do not duffer the same fate.

Insight would be welcome.
