It's possible that the above module doesn't match the
current version of Python, which is: 2.6.2 ....
CentOS 5.x has python-2.4.3 : All admin tools depend on version 2.4.3,
which should never be changed.
You can however have an extra python(2.6), like /opt/python26/bin/python2.6,
but only one 'python' is allowed in the PATH : Must be 2.4.3 .
? ? May be you installed python26 from the EPEL repo ?
And renamed /usr/bin/python26 to 'python' ? ?
