My first comment is that this does not work properly (or at all on Win32)

The problem is that $File::Find::name is the fullpath so if I try to clone say C:/Perl to C:/New mkpath is passed args like 'C:/New/C:/Perl/site/lib' which is not a valid path. You need to make the paths relative to $from. This will actually work and produce a clone where the new root $to contains exactly what $from does:

#!/usr/bin/perl -w
use strict;
use File::Find;
use File::Path 'mkpath';

#usage dirtreeclone fromdir todir   No trailing slashes 

my $from = shift || '.';
my $to =   shift || "$0-tmp";
my @dirs;

find (sub {push @dirs => $File::Find::name if -d},$from);

foreach my $dir(@dirs){
    $dir =~ s/^\Q$from\E//;
    mkpath("$to/$dir");
}
