Probably the file system containing /usr/lib/mailman/cgi-bin/ is mounted
with the 'nosuid' option so the SETGID bit on the wrapper is not effective.

You could work around this by changing the ownership of everything to
webuser:mailman where webuser is the user the web server runs the CGIs
as, but better to mount the filsystem suid.
