Thanks for fixing these. I didn't realize that the buildouts would break
because of my change. I should have though.

(I've also given up looking at the buildout perma-failures a long time ago)

I've done this.

This is a tricky issue, there are 2 parts:

    * Supporting python 2.5 in zope.schema is not hard, but will make
      the code quite ugly (no class decorator for implements)
    * I'm not sure if the next version of the ZTK will need to support
      Python 2.5

So there seem to be 3 options to fix this buildout issue:

    1. Point the ZTK trunk at the zope.schema 3.8 branch
    2. Make the zope.schema code uglier and support 2.5
    3. Declare that the next ZTK version drops support for 2.5 and stop
       the buildbot for Python 2.5 + ZTK trunk

I'm partial to option 1 to get the buildbot working and defer the Python
2.5/ugly code decision to later.
