Milter-greylist

I'm doing

./configure --with-user=greylist --enable-dnsrbl --with-libbind=/usr/local/lib

and getting the following message:

--enable-dnsrbl used but DNS resolver is not thread safe
Try installing BIND9 and using --with-libbind

I have BIND 9.3.2 installed.  Without "--enable-dnsrbl" it seems that it
is configured and compiled well (though with several warnings).
System is Linux 2.4 with gcc 3.3.4 and glibc 2.3.2

# ls -l /usr/local/lib | grep libbind

-rw-r--r--   1 root root 1979501 Jan  3  2006 libbind.so.4.0.2

What should I do?  Maybe reinstall BIND with some specific options (I
did "./configure --enable-libbind --with-libtool"), or add some options
to milter-greylist's configure?
