Just a heads up for anyone going down this path. You might want to add the following action. In library (e.g. in my case I’m working in /opt/ansible, so /opt/ansible/library), run:

for f in `grep -ri "/usr/bin/env python" * | cut -d":" -f1`; do sed -i ‘s//usr/bin/env python//usr/bin/env python26/g’ $f; done

before running make rpm. Otherwise you can do this after the fact in /usr/share/ansible

Don't do this. We have a much better answer already.

Just set ansible\_python\_interpreter as a group or host variable and it  
will override things at runtime. You can actually set  
ansible\_foo\_interpreter for any interpreter named foo, by the way, and  
it just works like magic (thanks to jkleint, IIRC).
