Nginx can't execute perl-fcgi？

Server NGINX
#1

Configure perl-fcgi on nginx.
Sourcecode compile FCGI、IO、IO-String、IO-All、Getopt,and install
them.
insert perl-cgi in nginx.conf,and start perl-cgi startscript.
But my web visit the cgi,it says that:

No such CGI app - /web/cgi-bin/test.cgi may not exist or is not executable by this process.
I test where havn’t a cgi file,then visit the doesn’t exist file.
It says that:

No such CGI app - /xxxx/xxxx/test.cgi may not exist or is not executable by this process.
yet.

How I can fix it?(I think my CGI does’nt execute.)
