Sure.

Correct.  I started out doing development with CVS HEAD python, but
got into trouble when I tried to run Zope with it, so I switched back
to py152.  The python-dynload-global was generated in the CVS HEAD
period.

Correct.  I have not tried a build with CVS HEAD python for a while,
so things might have changed.  It looks like Distutils change a lot
all the time.

It need both, but if you start with the a1 zope-perl-dist you need to
manually backport the python-dynload-global patch.  I'll include the
following 1.5.2-version of the patch with the next release.

Thanks for you feedback!
