Hi

1) report bug to rt://Alien-LibXML author, share link to this thread maybe, and you're done

Then forget that Alien-LibXML exists

2) install XML::LibXML

cpanm --look XML::LibXML

edit Makefile.PL

and replace this with your own paths

  CCFLAGS => Alien::Libxml2->cflags . " $Config{ccflags}",
  LIBS    => [ Alien::Libxml2->libs ],

Once upon a time I used something like

perl Makefile.PL INC="-IC:\citrusperl\mingw\xminms\include  -IC:\citru
+sperl\mingw\xminms\include\libxml2 " LIBS="-LC:\citrusperl\mingw\ming
+w32\lib -LC:\citrusperl\mingw\xminms\lib -lxslt -lxml2 -liconv -lws2_
+32 "
