apache2: mod_cgi.so missing

[wsiegrist@…]

I installed apache2+workermpm on 10.5.3. When trying to run apache, it complained about missing mod_cgi:

bash$ /opt/local/etc/LaunchDaemons/org.macports.apache2/apache2.wrapper start
httpd: Syntax error on line 104 of /opt/local/apache2/conf/httpd.conf: Cannot load /opt/local/apache2/modules/mod_cgi.so into server: dlopen(/opt/local/apache2/modules/mod_cgi.so, 10): image not found

After further searching, threaded MPMs cannot be used with mod_cgi, so that module does not get built when using workermpm. There is an alternate module, mod_cgid which should be used instead. This probably warrants a patch to httpd.conf in the workermpm variant.
