Mailman (the GNU Mailing List Manager) Unlike other SlackBuilds which have a /usr installation prefix, this script will install Mailman to /opt/mailman instatead. This is done to simplify the build process since Mailman attemps to install itself into many non-standard directories in the prefix directory. Therefore, it is installed as a self-contained and easily-removable location in /opt. It may be that you wish to keep Mailman's lists database in /var/mailman instead of /opt/mailman/var/mailman, in which case you should adjust the VAR_PREFIX variable at runtime. For example: VAR_PREFIX="/var/mailman" ./mailman.SlackBuild This SlackBuild assumes the webserver group name to be "apache", which should work just fine for you if you have the Slackware httpd package installed. If you wish to use a diffent webserver then set the group name accordingly by passing is to the script via the CGI_GID variable at runtime. Eg: CGI_GID="lighttpd" ./mailman.SlackBuild This script also expects there to be a user and group called "mailman", with uid and gid of 204 (see http://slackbuilds.org/uid_gid.txt): # groupadd -g 204 mailman # useradd -u 204 -d /dev/null -s /bin/false -g mailman mailman If you execute the script without creating this user and group, it won't build the Mailman package. NOTE: You must run /opt/mailman/bin/check_perms -f (using root) after installation/upgrade and before running mailman daemon to fix permission needed by this package.
