title: yum install error Centos 5
body: <p>I cannot find any information regarding the issue I am having so here it is.
  While trying to yum install php-pear (infact running yum at all) I run into this problem:</p>
  
  <p>There was a problem importing one of the Python modules
  required to run yum. The error leading to this problem was:</p>
  
  <pre><code>cannot import name canCoinstall
  
  Please install a package which provides this module, or
  verify that the module is installed correctly.
  
  It's possible that the above module doesn't match the
  current version of Python, which is:
  2.4.3 (#1, Nov 11 2010, 13:34:43) 
  [GCC 4.1.2 20080704 (Red Hat 4.1.2-48)]
  
  If you cannot solve this problem yourself, please go to 
  the yum faq at:
    http://wiki.linux.duke.edu/YumFaq
  </code></pre>
  
  <p>And as it says above - something to do with the module canCoinstall.  Does anyone know how I can fix this?</p>
