With a bit of help from the File:: modules I've come up with this code snippet 
use strict;
use warnings;

use File::Basename        'basename';
use File::Find::Rule      'find';
use File::Path            'mkpath';
use File::Copy            'copy';
use File::Spec::Functions qw/ splitdir catdir splitpath catfile /;

$::PROG         = basename $0;
my($orig, $new) = @ARGV;

die "Usage: $::PROG SRC DEST\n"
  unless defined $new and defined $orig;

my $iter        = find start => $orig;

while(my $ent = $iter->match) {
  if(-d $ent) {
    my $mode = ( stat $ent )[2];
    my @src  = splitdir $ent;
    my $dest =   catdir $new => @src;

    mkpath $dest => 0, $mode
      or die "$::PROG: Couldn't create '$ent': $!";
  } else {
    my @src  = splitpath $ent;
    my $dest =   catfile $new => @src;

    copy $ent => $dest
      or die "$::PROG: Couldn't copy '$ent': $!";
  }
}

Not having a plethora of systems to work with, I couldn't say how portable that is, but given the ubiquity of File::Spec it should be relatively reliable. However, I'd say in this case it'd probably be simpler just to have a switch-esque statement to call the appropriate system copying tool per system to get reliable and consistent recursive copying.
