Compiling textproc/xmltooling on NetBSD 8.1/amd64 fails with this error:

XMLToolingConfig.cpp: In function 'TXFMBase* {anonymous}::TXFMOutputLogFactory(xercesc_3_2::DOMDocument*)':
XMLToolingConfig.cpp:182:41: error: invalid new-expression of abstract class type '{anonymous}::TXFMOutputLog'
             return new TXFMOutputLog(doc);
                                         ^
XMLToolingConfig.cpp:132:11: note:   because the following virtual functions are pure within '{anonymous}::TXFMOutputLog':
     class TXFMOutputLog : public TXFMBase {
           ^

I have not the slightest idea what this means...

FWIW: Compiling the package with lang/gcc8 on NetBSD or GCC 9.2.0 on Solaris throws exactly the same error. Upgrading to xmltooling-1.6.4 yields the same result. I remember successfully building version 1.5.3 two years ago, but this version fails now in the same way. I guess this error is related to boost, which was probably at a different version when I was able to compile this package the last time.
