Since we see no other references to this array ref, I'm assuming this code is cut down from its full version. 
        if ( ! @{ $self->{dirs} } ) {
            return;
        }
        my $dir = shift @{ $self->{dirs} };
        if (-d $dir) {

Add a proper declaration for $olddir above, and: 
          if ($oldir){
            $self->{level} += 
                ($dir=~tr!/!/!) - ($olddir=~tr!/!/!);
          }
          $olddir=$dir;

I haven't tested this, but the idea is that, since the paths are all absolute, a change in level means a difference in the number of path seperators. (You might want to use a more portable form of the seperator than a literal "/".)
