Thanks,

in the end (and with great help of Adam Jackson and others) 
I have managed to make it work (both of these variables don't 
have much of documentation).

Well, the problem is that I wouldn't. Just after packaging mako, 
I found I have to port also backport-collections, 
total_ordering, generate 700 lines of patch to make it work, and 
I have made it work 
(https://copr.fedoraproject.org/coprs/mcepl/piglit-el6/), just 
to found out (when trying to upgrade on even more recent piglit) 
that I would have to upgrade NumPy as well. This hole does have 
no end.

Best,
