This is a newbie question, I realise, but I'm trying to get a branch of mailman 3 working, so that I can add in some support for LDAP/mailAlternateAddress lookups, which I know will be useful for our site, and hopefully useful for others.
I've worked through the bzr install and finally have my own separate install of Python 2.7 with bzr2.3, just for mailman. However, 2.7 doesn't appear to work - should I be using Python 2.6 instead? Is there a way to get it working with 2.7? 
Incidentally, are there plans to allow installs to a different location? If you specify a prefix to install under, it checks for the presence of the Python site-packages and fails if they're not present. Is it going to be a requirement to install under the Python tree, or is this just for development?
 Debian/lenny has Python 2.5, which is too old. It does have bzr 2.0, which is apparently recent enough, however each installation of Python expects bzr to be in the same bin/ directory as the python binary, so one must build bzr independantly for each Python install. This isn't very intuitive for someone new to this tool.
