hi shane, i don't think so.
i modified ZConfig/loader.py, lines 203 and following:

        try:
            ignored = __import__(package)
+            print "ignored: %r" % ignored
        except ImportError, e:
            raise ZConfig.SchemaResourceError(
                "could not load package %s: %s" % (package, str(e)),
                filename=file,
                package=package)
        pkg = sys.modules[package]
+        print "pkg: %r" % pkg
        if not hasattr(pkg, "__path__"):
            raise ZConfig.SchemaResourceError(
                "import name does not refer to a package",
                filename=file, package=package)
        return "package:%s:%s" % (package, file)


the debug prints:
ignored: <module 'ZODB' from
'/home/xlhost/zope/lib/python2.4/site-packages/ZODB3-3.9.0a12-py2.4-linux-i686.egg/ZODB/__init__.pyc'>
pkg: <module 'ZODB' from
'/home/xlhost/zope/lib/python2.4/site-packages/ZODB3-3.9.0a12-py2.4-linux-i686.egg/ZODB/__init__.pyc'>
ignored: <module 'relstorage' from
'/home/xlhost/zope/lib/python2.4/site-packages/RelStorage-1.1.3-py2.4.egg/relstorage/relstorage.pyc'>
pkg: <module 'relstorage' from
'/home/xlhost/zope/lib/python2.4/site-packages/RelStorage-1.1.3-py2.4.egg/relstorage/relstorage.pyc'>

so the imports seem to work fine, however pkg has __path__ attribute missing!

maybe that will help with debugging? btw. i also tried relstorage trunk
(did a svn co and replace the egg's files with the checkout files),
but that did NOT help.

best regards, jürgen herrmann
