Thanks to all the monks that helped me with this!

For the curious this is what it took to get Net::OpenSSH installed on Centos 7:

# yum install epel-release
# yum install perl-Net-OpenSSH
[download]

And now the salient portion of my ssh module looks thusly:

my $ssh;
my $key_path = $ENV{HOME} . '/.ssh/id_rsa';

if ( ops_cmd_status($cmd) ) {
   $ssh = Net::OpenSSH->new($cmd->{host}, user => $cmd->{user}, key_pa
+th => $key_path);
   if ( $ssh->error ) {
      $cmd->{status} = 'failure';
      ($cmd->{ssh_retcode}, $cmd->{ssh_retmsg}) = (0 + $ssh->error, ''
+ . $ssh->error);
   }
}

if ( ops_cmd_status($cmd) ) {
   ($cmd->{output}, $cmd->{std_err}) = $ssh->capture2($cmd->{command})
+;
   if ( $ssh->error ) {
      $cmd->{status} = 'failure';
      ($cmd->{child_retcode}, $cmd->{child_retmsg}) = (0 + $ssh->error
+, '' . $ssh->error);
   }
   chomp $cmd->{output};
   chomp $cmd->{std_err};
}

Thanks again for everybody's help.
