I haven't looked through all of your script, so just two small hints:

1 Use lexical variables as file handles: 

open my $handle, '<', $filename
    or die "Can't open '$filename' for reading: $!";
while (<$handle>){
    ...
}
close $handle

This will avoid trouble if you forget to close a filehandle, or call functions recursively while a handle is still open

2 If you want to dump the output of an array, set a backslash in front of it: 

my @list = qw(foo bar baz);
print Dumper \@list;
__END__
VAR1 = [
          'foo',
          'bar',
          'baz'
        ];

This makes it clearer that it's one variable, and you can easily see where it ends.
