Mailman CGI error!!!

The Mailman CGI wrapper encountered a fatal error. This entry is being stored in your syslog:

Group mismatch error. Mailman expected the CGI wrapper script to be
executed as one of the following groups:

but the system's web server executed the CGI script as group: "nginx".
Try tweaking the web server to run the script as one of these groups:
[apache],
or re-run configure providing the command line option:
