In the meantime, the hard drive on Vincent's box failed, so he
reinstalled the box completely.
Also he explained to me a lot of Mac things over the phone, so I think
I now understand what is going on with the dmg.

As such, I have updated my instructions in my release helper repo:


by the following paragraph:

First prepare the Mac build box as follows:

* Install Python 2.5, 2.6, 2.7 from python.org using the dmg disk image
* Install setuptools and bdist_mpkg into all these Pythons
* Install Paver into the default Python

Tip: Add the /Library/Frameworks/Python.framework directory into git
and commit after each installation of any package or Python. That way
you can easily remove temporary installations.

And you need sudo access to do those. If your user is an admin, then
it can do it, otherwise it can't.
So one can only use a Mac, which has the above setup installed. With
that, my Fabfile can then do the rest.

So I just built the following binaries:


and uploaded to:


So I think we are all set here. Ralf, would you be willing to build
the final binary on 10.6? I don't think you have to do it for this
rc1, but I am going to release rc2 now and for that it would be nice
to have it.
