我刚刚在 Ubuntu Server 12.04 上从 .deb 文件安装了 webmin，一切顺利。
我登录了 Web 界面并查看了“Perl 模块”页面。有一个建议的模块但未安装。我选择了它并按下安装，然后出现以下错误：

Installation of Authen::Libwrap failed. Check the output above and try installing manually.
You can also install the module from CPAN with the command perl -MCPAN -e shell.
ExtUtils::CBuilder我认为我已经从 cpan 命令行成功安装，但在安装“Authen-LibWrap”时仍然出现相同的错误。
有人可以帮忙吗？

Ubuntu 需要安装这些才能运行：
sudo apt-get install libwrap0 libwrap0-dev
