Lovely, it's not configurable... I got to fix this upstream but it worries me because it does not include an explicit license, which is not good. Although I could probably argue that mailman is misconfigured by default if it saves logs in /var/lib — nevertheless this is a bug that has to be fixed, will try something.
Okay this should be solved in 2.0.9-r1. The paths are now configurable, and I changed the default configuration file to point to Gentoo's default for mailman.
It works now, thanks!
