I'm using elasticsearch ver2.4.0, followed the "[Installation from source"](https://www.elastic.co/guide/en/elasticsearch/client/curator/current/python-source.html) to install curator, but hit below error.

Python 2.6 is very outdated. It's entirely possible that you do not have enough of a patch-level to install some of the dependencies. I say this because all of the errors listed are in the `/usr/lib64/python2.6` path. What operating system is this? Something else to be concerned about is that these older versions of Python lack the most recent security patches for SSL. This doesn't matter as much if Curator will be connected to localhost, or in a private network. If you do plan on connecting via SSL, however, I recommend using the most recent patch-level of Python 2.7 or 3.5. The new [binary packages](https://www.elastic.co/guide/en/elasticsearch/client/curator/current/yum-repository.html#yum-binary) of Curator available via the [yum repository](https://www.elastic.co/guide/en/elasticsearch/client/curator/current/yum-repository.html#_repository_configuration_2) are recommended for these older installations, as they bundle all of the most up-to-date libraries, ensuring that you can connect securely, and also that there are no conflicts with other versions of python modules. ---

Thanks a lot Aaron, I'll try it out. ---
