我需要在运行python 2.6（旧版CentOS版本）的机器上从源代码安装软件包rpy2。 rpy2的当前版本是2.5，它仅在python＆gt; = 2.7上兼容。
从official documentation开始，我查看了最后几个版本，发现2.2是最后一个在Python 2.6上运行的版本。太糟糕了，它不会安装：
# python26 setup.py build install
running build
running build_py
running build_ext
Traceback (most recent call last):
File "setup.py", line 441, in <module>
[os.path.join('doc', 'source', 'rpy2_logo.png')])],

rc = RConfig.from_string(rconfig, allow_empty = allow_empty)

+ '\nin string\n' + string)

解：
我需要安装以前版本的R（2.12或2.13），如the docs
