Who can help me to solve running .pl (perl) in nginx

my os is ubuntu, and I follow the http://wiki.nginx.org/SimpleCGI but
when I visit the pl(perl) file, the pl(perl) file will be a defunct
process. And the cpu will reache the 100% by the cgiwrap-fcgi.pl …
how can I fix this problem? And how can run the perl file in nginx?
