[Fail2ban-users] fail2ban start error

[SAMUEL G. <so...@ho...>]

Hi,
I installed fail2ban on a Centos 6.4 64 bit running server using the sudo yum install fail2ban command, and I am having trouble starting it.When I type $ sudo fail2ban-client start I get the following error:
Traceback (most recent call last):    File "/usr/bin/fail2ban-client", line 34, in <module>       from common.version import versionImportError: No module named version
is there something else I need to configure before I start fail2ban?
Thanks
