You will eed to patch ExternalFile to use Zope3-style interfaces. E.g.,
from Interface import Interface
patch it to be:
from zope.interface import Interface
Their may be other changes required, as well, depending on how the
product uses the interfaces. (Later: I've done the patch, at least to
the extent of getting the appserver to start: see attachment).

You need to install the MySQL-python package into your virtuaenv:
$ bin/easy_install MySQL-python

The ExternalFile product is quite old, and could likely use a maintainer
to keep it up to date. I haven't seen Craeg Strong (the author) around
in Zopeland for quite some time: he might be happy to hand it over to
you as a person who still needs to have the product work.
