Python 在Linux上安装Rpy2时出错

我正在尝试在Linux上安装Rpy2版本2-2.2.1，我得到以下错误

下面是我看到的两条错误消息：

/usr/local/msg/lib64/R/bin/exec/R: error while loading shared libraries: libg2c.so.0: cannot open shared object file: No such file or directory

    rversion = m.groups()[0]
AttributeError: 'NoneType' object has no attribute 'groups'

以下是完整的输出：

所以我试着把它安装在网络驱动器上，但是从一台我从未安装过R的机器上。当我从正确的机器上安装时，问题就消失了。

rpy2的setup.py可能会更优雅地失败。。。或者可能是在更新的版本中，最新的rpy2版本是2.3.10。注意：不管是谁做的，都可以在没有评论的情况下直接投票。。。
