I guess you did not see where I asked that folks also send email to my
pkgsrc alias so that I would be more likely to see their messages.

Actually, just because they are in pkgsrc does not mean that you have
to use them. ;) And there are some advantages to using pkgsrc.

Granted, installing Zope by hand is fairly easy right now, and as you
say, is mostly Python + a few C parts. But, by putting it into
pkgsrc, you can also use the buildlink framework to make sure that all
the dependency/linking issues for things like Python are handled.

Ahh... using pkgsrc, I had no problems getting the Python modules for
Zope+CMF+Plone and the handfull of other products I installed. It was
even smart enough to make note of the fact that there was something
else depending on MySQL 4 and those other packages.
Only problem I have see so far is a pair of python module dependencies
which were not building, and those may have been due to the machine I
was building/testing on being a hybrid of 1.6.2 and 2.0.

Yep. Already thought of that, and it is handled via a variable.
Right now, I have two such trees, with their own instances.

Ah, but as I said, you do not have to use pkgsrc, or change to the new
version when pkgsrc changes. And your point about the version issues
is a strong argument for pkgsrc. After all, why should everyone have
to figure out that particular combinations of Python + Zope + Plone do
not work?? Anyone maintaining the new pkgsrc packages (I certainly
will be submitting them with my name as the maintainer) will hopefully
have the intelligence, time and knowledge to make sure that things
work before committing changes.
So, in summary, here are some good reasons for having them in pkgsrc.
- It can maintain dependencies for you, making sure you have a good
combination of OS+Python+Zope+CMF+Plone+xxx+yyy without you having
to take the trouble to do this manually.
- Not mentioned above, pkgsrc helps you keep track of where all the
files (outside of the Zope instance directories) are located, so
that you can cleanly remove them when you want to remove Zope or
want to upgrade it.
- Not mentioned above, pkgsrc also helps you keep track of modified or
corrupted files (see pkg_admin for more info)

Very much on-topic for both the group and the thread, and thanks for
