Hi Simon.  I can reproduce this with Python2.7 on Ubuntu 10.10.  This is
caused by the locknix package, which depends on setuptools_bzr.  The issues
you've identified with bzr on Python2.7 are causing the setuptools_bzr
dependency to fail.

The upstream fix is to remove this dependency from the locknix setup.py file.
I'll try to do that in the next day or so.  Once I release a new locknix
package, it should work again.  (Side note: I want to move locknix into the
flufl namespace package, so things will change a bit more at some point in the
future, but I won't block a quick fix on that reorganization.)

Can you provide the commands that failed for you?  I'd like to try to
reproduce this.  If you can, submit a bug report.

Ideally, the 'mailman' package will be installed under site-packages (or
dist-packages for the Debuntudes in the audience ;) and you'll have access to
just the few command line scripts in /usr/bin.

Alternatively, it should be possible to build Mailman 3 in a virtualenv to
stick it anywhere you want, though I haven't tried that in a while.
