As to issue of the script running on your mac, but not on the server as a CGI :
this may not be due to the '-w' switch a such, but if you insist on not
using it you'll find people will be reluctant to help you, (see below)

A generic 500 error check list is:

* is the path to perl correct (in the she-bang line)
* does the script have the correct permissions to run
* if you transferred it from another machine using a different OS, are you
sure the line endings  are correct?

If these three steps don't solve your problem you need the error logs

Then the next thing to do is to check out the DOCs which come with all Perl
distros, because in all of the Perl NG and mailing lists, CGI related
postings are notorious for being trivial and  easily solved (by using '-w',
'use strict;' and checking the 3 things above). In keeping with this, this
is the same reason why MacPerl has a separate CGI list, (it didn't always).
In the perl community in general the minute you post anything in which it's
apparent that you haven't read the docs and you haven't followed any of the
basic guidelines set out in the FAQs because you haven't read them, people
either don't reply to your posting or get downright nasty/abusive, because
they've seen the same kinds of posting over, and over again, and consider
them only marginally better than spam (but only beause the posters aren't
trying to squeeze money out of them) :~)


(from POD FAQ 9: )
My CGI script runs from the command line but not the browser. (500 Server
Error)

If you can demonstrate that you've read the following FAQs and that your
problem isn't something simple that can be easily answered, you'll probably
receive a courteous and useful reply to your question if you post it on
comp.infosystems.www.authoring.cgi (if it's something to do with HTTP,
HTML, or
the CGI protocols). Questions that appear to be Perl questions but are
really CGI ones that are posted to comp.lang.perl.misc may not be so well
received.
