Yes ! That works for me too.
I got confused, I though that data-accessor was part of the template
library and so therefore maybe there was a problem with the versions
being used in debian.
Looks like data-accessor stands on it's own, and that it's really a
problem with chart not being able to use the most recent version of
data-accessor, is that right ?
