Check your "Shebang line".

CGI scripts should start with something like: 

#!/usr/bin/perl
print "Content-type: text/plain\n\n";
print "Hello World!\n";

(Assuming your web server is *nix. If it is Windows, the path to perl needs to be set appropriately: #!c:\path\to\perl.exe. )

For effective debugging, if you use IE, you should turn off "Friendly HTTP error messages" because they hide root cause.
