Hi Aurélien Bompard! Thank you for patching. Now this error does not occur. But I stil can't build the mailman with the error I reposted in the bottom of my bug report: --- (venv)[root@host mailman-bundler]# buildout Develop: '/usr/local/src/mailman-bundler/.' warning: no files found matching '*.in' under directory 'mailman_bundler' warning: no files found matching '*.in' under directory 'deployment' warning: no files found matching 'deployment/mailman-web.logrotate.conf' Updating mailman-web.
