Well, have you executed your script?
You should see the output that will be sent to the browser.
The script you are trying compiles but produces NO output.
Try this:
#!/usr/bin/perl
print "Content-type: text/html\n\n";
print "<html>";
print "<body>";
print "<h2>I just wrote my first web page using Perl!</h2>";
print "</body>";
print "</html>" ;
Run the script first from the command line. You should see output.
If your server doesn't display it as a webpage check the permissions etc.
In general cgi is quite simple. All standard output will be directed to the
browser and all errors should go to error_log.
So just executing the cgi script/program should produce output on the command
line.
