# yum update There was a problem importing one of the Python modules required to run yum. The error leading to this problem was:
/lib/libgssapi_krb5.so.2: symbol krb5_build_principal_axt, version krb5_3_MIT not defined in file libkrb5.so.3 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: 2.6.2 (r262:71600, Aug 21 2009, 12:22:21) [GCC 4.4.1 20090818 (Red Hat 4.4.1-6)]
