the sole script I found in my path:

Hi Benjamin,
I think the problem is that you have SQLAlchemy-0.4.0beta6 installed but
Elixir currently is currently only compatible with SQLAlchemy 0.3.x. You
can run the following commands to downgrade:
easy_install -m SQLAlchemy
easy_install SQLAlchemy==0.3.10
Btw, I'm planning to release Posterity 0.6 in a few days (probably on
Monday). So trunk is pretty stable and contains a couple of new features
(filters and pop3 message downloading) so it might be a good idea to
give it a try. Trunk will also make sure the correct SQLAlchemy version
is installed.
A quickstart guide for trunk can be found here:
http://posterity.edgewall.org/wiki/Documentation/quickstart.html
And for Posterity 0.5:
http://posterity.edgewall.org/wiki/Documentation/0.5.x/quickstart.html
Cheers,
Jonas

Thanks. It solved the issue.
Then I tried this:
$ posterity-admin account bsergean
and this:
$ posterity-admin serve
But it blows, because of the deploy module. Maybe a downgrade here too
would be usefull. It looks like using svn would be a good idea. I will
try it, especially because pop3 is a must have for me. (I might try
your package with my gmail account).
Thanks,
Benjamin.

release I forgot to add PasteDeploy to the dependency list. Running
"easy_install PasteDeploy" should solve that problem.
But since you want to test the pop3 support the trunk version is your
only option until 0.6 is release.
Just keep in mind that the quickstart instructions are slightly
different:

What do you think ?
Maybe self.parser.error is not really the good way to report error.
Are you using the logging class to do that ?

This is very weird. If I understood you correctly you get this traceback
when you run "posterity-admin fetch" but not "posterity-admin serve"?
But if I interpret the above traceback this exception is raised very
early on, during the import of "posterity-admin" entry point. So the
exact same code path should be shared by both the "serve" and "fetch"
admin commands...
Btw, I'm thinking about dropping the sqlite support since unlike
postgresql, mysql and most other databases sqlite doesn't support
foreign keys. The current database scheme relies on "ON DELETE CASCADE"
and "ON DELETE SET NULL" constraints. Sqlite is a very nice database,
especially since it's very easy to use, but I doubt that it's the best
choice for most people when it comes to hosting email accounts in a
production environment. Most people are probably better of using other
databases with better concurrency support. Does that sound reasonable?
(btw, the same goes for the mysql myisam database engine, which also
lacks foreign key support)

Maybe I run both command in two terminals ... I'll try again monday on
my work machine. The fetch worked here at home, maybe because there is
no firewall on the pop gmail port.

I don't know a lot about database so I'm sure you know better. Just
that there is no db admin with sqlite.
