IPv6 support

[任晓磊]

I have a VPS that using tunnelbroker service provided by HE.net, and I
can 'wget -6' to retrieve ipv6 sites' content. Someone told me that he
cannot access my website served by nginx through IPv6 network, while
he can access the 22/tcp SSH port, and can ping6 my VPS. Is there any
compile option to enable IPv6 support?
My version is 0.6.32-3+lenny3 provied by debian, and nginx -V results:
~# nginx  -V
nginx version: nginx/0.6.32
configure arguments: --conf-path=/etc/nginx/nginx.conf
--error-log-path=/var/log/nginx/error.log
--pid-path=/var/run/nginx.pid --lock-path=/var/lock/nginx.lock
--http-log-path=/var/log/nginx/access.log
--http-client-body-temp-path=/var/lib/nginx/body
--http-proxy-temp-path=/var/lib/nginx/proxy
--http-fastcgi-temp-path=/var/lib/nginx/fastcgi --with-debug
--with-http_stub_status_module --with-http_flv_module
--with-http_ssl_module --with-http_dav_module
