I’m trying to switch to accelerate mode and I’m having trouble with my CentOS 5 clients (5.9 to be exact). I’m using the Ansible 1.3 release.

It works ok for CentOS 6 clients, but for CentOS 5 I get the following:

This of course does not happen if I turn accelerate mode off. What am I missing?

Thanks!

Could you please open an issue for this on github? That is syntax specific to python 2.6, which I will remove (it’s not really doing much of anything right now).

Thanks!
