nsgmls: Can't call method "value" on an undefined value

I compile wpa_supplicant-2.7 and ran into a problem.
Error:

...
nsgmls:/root/hostap/tmp.build_release/wpa_supplicant-2.7/wpa_supplicant/doc/docbook/eapol_test.sgml:196:10:E: element "TITLE" undefined

make: *** [Makefile:13: man] Error 8

line 249:

if(defined($_[0]->attribute('LANG')->value)) {
          $manpage_lang = $_[0]->attribute('LANG')->value;
        }
        else {
          $manpage_lang = '';
        }
})

What should I do? Developers are silent for a long time!
