I installed relstorage using the instructions for easy_setup, i.e.
'easy_install RelStorage'. I realized as I read through more of the
instructions that this likely put the relstorage modules in my python home
rather than in my zope software home. I don't know if this would have caused
the error I am seeing.

However, after reading more through the instructions, and watching
easy_install do its magic, I reached a point where I make a new zope
instance, then when in to that instance home and modified the zope.conf  to
use relstorage instead of filestorage, I was ready to start my new instance.
I was disappointed to have a traceback just running zopectl. I ran
$INSTANCE_HOME/bin/zopectl

and got the following traceback:

AttributeError: 'module' object has no attribute 'Surrogate'


for more information, there is another zope instance running on this machine
however there is only 1 zope_home. Furthermore, what I couldn't discern from
the install instructions for relstorage was configuration for postgresql.
Since the instructions were silent, I assumed I at least needed a pg user
for zope to connect as, and a database to contain the zodb. So I created
these in pg so the dsn in zope.conf would at least have something valid to
connect to.

Any adivce?

I think I will need to back out of what easy_install did to my pythonhome --
is there an easy way to undo what easy_install did ?
