在全新安装的ActivePython-2.6上，pip提供了导入错误

我在虚拟机上安装了Cent OS，它附带Python 2.4开箱即用。我需要安装Python 2.6，所以我从ActivePython安装了一个单独的Python二进制文件，它将自己安装在不同的目录中。当我运行PIP（/opt/ActivePython-2.6/bin/pip）我得到这个错误：在全新安装的ActivePython-2.6上，pip提供了导入错误

# pip 
Traceback (most recent call last):

    import urllib2

     import hashlib 
    File "/opt/ActivePython-2.6/lib/python2.6/hashlib.py", line 136, in <module> 
    md5 = __get_builtin_constructor('md5') 
    File "/opt/ActivePython-2.6/lib/python2.6/hashlib.py", line 63, in __get_builtin_constructor 
    import _md5 
ImportError: No module named _md5

我以前从未见过这样的错误，我不明白为什么它会尝试调用_md5当库只是“MD5”。当我尝试将_md5.py链接到md5.py时，我得到的错误是ImportError: No module named _md5。

_md5是md5.py导入的基础编译C库;这里使用C库的包装器来提高速度。 – 2010-12-03 22:42:59

在/opt/ActivePython-2.6中找到_md5.so并在其上运行ldd。是啊。

安装EPEL，通过yum安装python26，玩得开心。
