mono-3.4.0 源码安装时出现的问题 [do-install] Error 2 [install-pcl-targets] Er

Mono 3.4修复了很多bug，继续加强稳定性和性能（其实Mono 3.2。8 已经很稳定，性能也很好了），但是从http://download.mono-project.com/sources/mono/ 下载官方提供的源码安装Mono3.4 出现如下错误：

这是由于官方的mono源码包缺少个文件，所以会出错，可以下载我的云盘上共享的文件 http://pan.baidu.com/s/1eQ452Ie，参照这篇文章《CentOS 6.3下 安装 Mono 3.2 和Jexus 5.4》下载安装就没问题了。
