Try to register the template for the class:
z3c.layer.pagelet.browser.NotFoundPagelet

instead of for the:
zope.publisher.interfaces.INotFound

The INotFound interface doesn't need a template, but the
pagelet class needs one.

e.g.

<z3c:template
  template="notfound.pt"
  for="z3c.layer.pagelet.browser.NotFoundPagelet"
  layer="vortex.layer.IVortexBrowserLayer"
  />

> but when I trigger, e.g., a not found error I get:

The z3c:pagelet register via zcml a new class based on your
class attribute NotFoundPagelet given from
z3c.layer.pagelet.browser.

This is the same as the <browser:page> directive does.

Don't worry about this. That's correct.
