It would be easiest to just render the templates natively in Mako
rather than trying to use render. Buffet is tied really closely to
Pylons and entry points, which means you have to have the exact right
environment configured in order to use it. Buffet is also deprecated
in Pylons 0.9.7-beta, so it's not worth spending time trying to get it
to work.
Your best bet is to create a Mako template loader as described in the
Mako manual, passing it the template directory (myapp/templates) and
cache directory (myapp/data/templates).
For template variables, it's easiest to put them in a dict and pass
that to Mako's render method. You could also try using pylons.c and
the render_mako function in Pylons 0.9.7-beta.
