- Operation on GAE was broken, presumably because the

  ``repoze.bfg.configuration`` module began to attempt to import the
  ``repoze.bfg.chameleon_zpt`` and ``repoze.bfg.chameleon_text``
  modules, and these cannot be used on non-CPython platforms.  It now
  tolerates startup time import failures for these modules, and only
  raise an import error when a template from one of these packages is
  actually used.
