Doh, that line should have read:
from chameleon.genshi.loader import TemplateLoader

That depends. Personally I use chameleon.genshi since I prefer Genshi
syntax over zpt. If you want to use the Zope page template syntax you'll
want to replace chameleon.zpt.

Hm, the chameleon.zpt template has not seen as much love as the
chameleon.genshi version so it might have broken somewhere. Can you test
if chameleon.genshi works for you? If so I'll look at fixing up the
chameleon.zpt version.
