Bug 611029 (http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=611029) has been closed with a comment that "We believe that the bug you reported is fixed in the latest version of libcpan-meta-yaml-perl, which is due to be installed in the Debian FTP archive:",
but that package does not have anything to do with the biniax2 package, as far as I understand.
I have checked, and that comment was most probably intended to bug 611209, see http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=611209 so it is most probably a typo in the address field. Please reopen the bug in the biniax-2 package and close the other one instead.
