AFAIK Zope page templates use RestrictedPython which doesn't work on 2.5
for nontrivial reasons (the different AST implementation).

On the other hand, http://wiki.zope.org/zope3/Zope3UsingPython25 claims
zope.pagetemplate (and zope.tal) have been successfully ported to 2.5,
so I don't know.

Also, you don't *have* to use RestrictedPython in your templates.  These
were designed for Zope 2 where end-users could upload templates
containing Python code through a web form.  It isn't hard to disable the
RestrictedPython dependency and use zope.pagetemplate in trusted mode.
