Red Hat Enterprise Linux as Release 4 (nahant Update 4) Yum and libaio Installation

Red Hat Enterprise Linux as Release 4 (nahant Update 4) referred to as as4.

Required to run yum. The error leading to this problem was:

/Usr/lib/python2.3/Site-packages/celementtree. So: cannot open shared object file: no such file or directory

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
Current version of Python, which is:
2.3.4 (#1, Feb 18 2008, 17:16:53)
[GCC 20060404 (Red Hat 3.4.6-9)]

If you cannot solve this problem yourself, please go
The yum FAQ:
Http://wiki.linux.duke.edu/YumFaq
