Comment 1 for bug 432115

Good points, thanks! I've updated the Grok 1.0 branch to use the newer versions (and trunk)

I'm not sure what needs to be done to make simplejson compile its optional C extension by the way (on Windows hopefully it'll fall back to the pure_ptyhon version).

(Note that we do allow individual users to re-pin to newer versions in their buildout.cfg, so you're not entirely stuck.)
