Actually, you don't need Perl at all...

<!--#echo var="REMOTE_ADDR"-->

But I have to wonder ... how are you tallying the results of the poll? If you're using a Perl CGI, why do you need to access the REMOTE_ADDR beforehand when it should be available to your script as $ENV{'REMOTE_ADDR'}? It seems redundant to me to use SSI at all ...
