chunkin module is not working

[Yanxin Z.]

I am trying to use chunkin module in nginx, which is
https://github.com/agentzh/chunkin-nginx-module
I have the problem to use it.
I add "chunkin on" inside server config.
However, when I turn on nginx server, i enountered the error:
[emerg]: unknown directive "chunkin" in ./conf/nginx.conf:36

Another question is test cmd:
I have bunch of these errors:
..........
t/pressure......dubious
        Test returned status 2 (wstat 512, 0x200)
t/random........Can't locate Test/Nginx/Socket.pm in @INC (@INC
contains: inc lib t/lib /etc/perl /usr/local/lib/perl/5.8.8
/usr/local/share/perl/5.8.8 /usr/lib/perl5 /usr/share/perl5
/usr/lib/perl/5.8 /usr/share/perl/5.8 /usr/local/lib/site_perl .) at
t/lib/Test/Nginx/Socket/Chunkin.pm line 5.
BEGIN failed--compilation aborted at t/lib/Test/Nginx/Socket/Chunkin.pm
line 5.
Compilation failed in require at t/random.t line 4.
BEGIN failed--compilation aborted at t/random.t line 4.
..........

Could you help me to figure out the problem?
Thank you so much.
Yanxin
