I would recommend using buildout, most people do, if you have problems
it helps to be in the main stream.

This is a source distribution that a binary egg will be automatically
built from. As you are using virtualenv you should be able to
easy_install Products.ZSQLMethods in the same way you installed Zope2.
(I hope you have some way of ensuring a consistent known good set of
packages equivalent to the buildout versions.cfg, without it you are
unlikely to get a working system.)

On my development machine I have a virtualenv python (using
--no-site-packages) which I use to run buildout's bootstrap.
