If the script runs from command line look at the first line printed by the
script on your screen. The line should be "Content-Type: text/html"
depending on the content type. Before the first content line starts an empty
line is needed. The corresponding line in your perl source code must be

print "Content-Type: text/html\n\n"; 

You wondered about the first line in your perl scripts (#!/usr/bin/perl).
This is a typical feature of Unix shells. The first line of a script is the 
command line call of the program (with options) to execute the script itself.
This feature is similar to registering a file extension in Windows 95/98/NT.
If you use the script with a Windows version of perl this line is ignored.
But if you want to publish your perl stuff and it should work platform
independant (also on a Unix machine) do not delete this line.

I added a simple script to print out your CGI-environment. It is tested and
should run at once.
