Hi, here is a Net::SSH2 sftp script that works. I just verified it. This shows how to do a login with rsa keys, the password has been changed of course. Works on latest Slackware linux, which is pretty standard generic linux. 
#!/usr/bin/perl
use warnings;
use strict;
use Net::SSH2 qw(LIBSSH2_CHANNEL_EXTENDED_DATA_MERGE
                        LIBSSH2_CHANNEL_FLUSH_ALL
                        LIBSSH2_HOSTKEY_POLICY_ASK);

my $pass = 'rumpelstiltskin';
my $ssh2 = Net::SSH2->new( debug => 1 ); 
$ssh2->trace(-1);
$ssh2->timeout(5000);

$ssh2->connect('my.net') or $ssh2->die_with_error;

$ssh2->auth_publickey('me',
                 '/home/me/.ssh/id_rsa.pub',
                   '/home/me/.ssh/id_rsa',
                $pass );


 my $sftp = $ssh2->sftp();
 my $fh = $sftp->open('/etc/passwd') or $sftp->die_with_error;
 print $_ while <$fh>;


return 0;

__END__
