lol - sorry to point out the obvious, but ya never know ;) - have seen 
worse/done worse myself...

Anyhow, try modifying the script so it just outputs something to the console, 
see if cron logs/emails the output or not, then take it step-by-step from there; 
have it actually print out/echo the command(s) your script will run, then you 
can verify the command works on the console, then go from there.

I have a (rather complex) backup script using rsync, written in Perl (yeah, I 
know I could have done what I did using shell or a cleaner setup - just Perl is 
easier ;) I synchronize serveral directories to effectively mirror a partition 
accross two data servers (/server, from server1 to server2). Here's my script 
for what it may be worth:

#!/usr/bin/perl -w

use strict;
use lib '/server/modules';

my $verbose = defined($ARGV[0]);
# pairs go: /server/{src/key} = /server/{dst/value}
# eg: 'profiles' => '' = /server/profiles (remote) to /server (local)

my %dirs = (	'profiles'=>'',
		'netlogon'=>'' );

open(LOG,">/var/log/rsync_nightly.log") || die "Couldn't create log file!\n";

foreach my $src (keys %dirs) {
	my $output = `/usr/local/bin/rsync -va --stats --delete 
rsync://server2/server/$src /server/$dirs{$src}`;
	print LOG $output;
	print $output if ($verbose);
