I use BBEdit to write scripts.

Begin to use code tags instead :)

not even the bottom line prints to the screen

I don't get the full meaning of this sentence, but I understand that you don't see the "I was Here!" message, correct? If so, your program is exiting at the die statement, but you don't see it in the browser - go look in the logs. If you want error messages be displayed in the browser, use CGI::Carp:

use CGI::Carp qw(fatalsToBrowser);

Now all fatal messages (triggered by die) will be output to the browser as well as the log file.
