Why execution of yum or rpm command gives an error "usr/lib64/librpmbuild-4.4.so: symbol gelf_getvernaux, version ELFUTILS_1.0 not defined in file libelf.so.1 with link time reference" ?

Issue

• Yum and rpm command are not working on the system.

• Execution of "yum udate" command gives following error messages on the terminal.

# yum update 

There was a problem importing one of the Python modules
required to run yum. The error leading to this problem was:

   /usr/lib64/librpmbuild-4.4.so: symbol gelf_getvernaux, version ELFUTILS_1.0 not defined in file libelf.so.1 with link time reference

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, Dec 22 2011, 12:12:01) 
[GCC 4.1.2 20080704 (Red Hat 4.1.2-50)]
