If you are on Windows, then you'll need to use Net::SSH::W32Perl. Try this instead:
#!/usr/bin/perl

use strict;
use warnings;
use Net::SSH::W32Perl;

my $host = 'localhost';
my $user = 'user';
my $pass = 'password';
my $cmd  = 'perldoc -f getpwuid';

my $ssh = Net::SSH::W32Perl->new(
          $host, 
          debug => 1,
          protocol => 2
);
$ssh->login($user, $pass);

my($stdout, $stderr, $exit) = $ssh->cmd($cmd);
print $stdout, "\n";

exit;
