从Perl连接到MongoDB时的编译错误

http://search.cpan.org/dist/MongoDB/lib/MongoDB/Tutorial.pod

我的目标是从Perl脚本连接到MongoDB数据库.我用cpanm安装了MongoDB：

$sudo cpanm MongoDB
MongoDB is up to date. (0.501.1)

我创建了一个名为loadRaw.pl的简单Perl脚本：

use strict;
use warnings;

use MongoDB;
use MongoDB::Connection;
use MongoDB::OID;

print "hellon";

当我尝试运行脚本时,我收到一堆错误：

$perl ./loadRaw.pl

看起来像MongoDB Perl模块(特别是Cursor.pm文件)有一些语法错误.如果我添加行使用Carp,第一批问题(与confess关键字相关的问题)就解决了;到Cursor.pm的顶部.但是,我认为我不应该这样做,而是我正在做其他错误的事情.此外,第二批错误(与has关键字相关的错误)不能通过包含Carp来解决.

还有其他人经历过这个吗？有任何想法吗？
