This error is explained mor fully in the FAQ at <http://wiki.list.org/x/4030645>

That's irrelevant. The message is telling you that the wrapper at /usr/local/mailman/cgi-bin/mmsearch (and probably all the others - do you get this error on any of Mailman's CGIs or just when you do an archive search?) has been compiled to expect to be invoked by the web server running as group 'apache', but the web server is invoking it as group 'mailman'.

In any case, the actual effective grout under which the CGI runs is 'mailman' because the wrappers are all SETGID and group 'mailman'.

It seems you may have something like

Group mailman

in your apache config. To make Mailman CGIs work, you need to either set the Group in apache to 'apache' or re run Mailman's configure and make install with the --with-cgi-gid=mailman.
