I don't think you get how the 'wanted' function works. It is run once for each file and directory in the tree you're searching.

If you don't want a global array to store these results, you have two choices: you can either make the wanted function do the work on each file, or you can change the structure of your program. The former might look like: 

sub main {
    findit();
    # dostuff($_) for @dirlist;
}

sub findit {
    find(\&wanted, shift(@ARGV));
}

sub wanted {
    return unless -d $_;
    # push(@dirlist,$File::Find::name);
    dostuff($File::Find::name);
}

sub dostuff {
    print "$_\n"
}

I commented out the lines in your code, so you can more easily see the change.

The latter solution might look something like this: 

sub main {
   my @dirlist;
   find( 
      sub { 
         return unless -d $_;
         push(@dirlist,$File::Find::name);
      }, 
      (shift @ARGV) 
   );

   dostuff($_) for @dirlist;
}

sub dostuff {
   print "$_\n";
}

I highly recommend the first approach -- it seems silly, in most cases, to build a list of files and then act on it when you can act on each file as you find it.
