time limit???

Hi guys,

Suppose I have a Perl (called from a crontab file) script that will
(basically) do something like 
this: 

$out=`lynx -dump http://lists.cpan.org/showlist.cgi?name=beginners`; 
open(OUT,">out");
print OUT $out;
close(OUT);                                                                    
$send_it=`mail me\@here.com<out`; 

OK, here comes the problem. What if the web page is down? lynx will 
keep trying for a while until it gives up or something. 
Is it possible to impose a time limit, like: execute $out, wait for 
45 seconds, if there was no response (lynx did not dump), exit(0); 

cheers, 
A
