Actually megrok.form works just fine with grok 0.13, I've just tested
it. It seems that the get_default_permission error only occurs when
megrok.kss is installed on a grok 0.13 buildout:

  File "/Users/dirceu/Documents/devel/grokenv/megrok.kss-0.2dev_r86018-py2.4.egg/megrok/kss/meta.py",
line 9, in ?
    from grok.util import get_default_permission, make_checker

    ImportError: cannot import name get_default_permission

I will try to fix it later this week; any help is welcome, since I'm
not using grok 0.13 yet (and grok.util.get_default_permission was
removed after grok 0.12.1).

Thanks for the detailed report. I think that the best approach is to
get megrok.kss working with grok 0.13 first; then we can test them
together on a grok 0.13 buildout.

Kenneth: you told me in pvt that you need only zc.datetimewidget for
your project. You should be able to use it easily without megrok.form
- just take a look on how megrok.form register and use
zc.datetimewidget on it's ZCML files.
