If the match fails, that $1 will be wrong. Never use $1 unless it's in the conditional of the match test. I'd change those two lines to: 
$logfile =~ /(.*)..\.tar.gz$/ or die "Bad non-match on $logfile";
my $dirname = $1;

Also, your "link/unlink" pair can be replaced by a simple "rename". They're equivalent under the hood, with a lot less duplication.
