In it's simplest form it's hardly different than the example shell  
script in the Distributed Monitoring Documentation. Your perl script  
will need to know the shortname and service description in nagios that  
it's submitting a result for as well as the return code and text to  
display. When all that is known a system call is all that's needed --

system("/bin/echo -e '$host_name\t$service_description\t$return_code\t 
$outputtext\n' | /usr/local/nagios/bin/send_nsca <nagois_host> -p 5668  
-c /usr/local/nagios/etc/send_nsca.cfg");

If you wanted to get more sophisticated you could open a pipe directly  
from perl to send_nsca and send to it's STDIN which would eliminate  
the slight overhead of the shell initiation. http://www.unix.com.ua/orelly/perl/cookbook/ch19_07.htm 
  has some safer options than a straight system call for this purpose.
