Concatenate them something like this:

my $out = '';
my $err = '';
foreach my $one(@cmds) {
  my ($stdout,$stderr,$exit) = $ssh->cmd($one) ;
  $out .= $stdout;
  $err .= $stderr;
  warn "'$one' has exit value $exit\n" if $exit;
}
print $out; # all the outputs concatenated
print $err; # all the errors concatenated
