Did you check which file is missing, e.g. compare ls -la with your programs output? Is it always the same?

I checked your program here (SuSE 10.2, perl 5.8.8) and was surprised to see that there was a delta of one file too! Problem was counting the output of ls -la | wc -l vs. perl yourprogram.pl | wc -l. The delta was caused by this line: total 84! Maybe...?

Update: This works here: 

#!/usr/bin/perl
use strict;

my %ls = map { chomp; $_ => 2 } qx{/bin/ls -1};

opendir(DIR,".") or die "cannot readdir here - $!";
$ls{$_}++ foreach  readdir(DIR);

my @where = ("","readir only", "ls only", "both");
foreach (sort keys %ls) {
  printf("%12s: %s\n", $where[ $ls{$_} ], $_);
}

__END__
readir only: .
readir only: ..
       both: file1.pl
       both: file2.pl
       both: path
