[Mailman-Users] "Mailman CGI error!!! Operation not permitted" - after upgrading Apache to 2.4

I've updated Apache to 2.4, and my mailman installation refuses to work with the following information:

Mailman CGI error!!!
The Mailman CGI wrapper encountered a fatal error. This entry is 

being stored in your syslog:

Operation not permitted

The only things I see in logs is basically the same as above:

Jun 25 11:59:37 web1 Mailman cgi-wrapper (listinfo): Operation not permitted Jun 25 12:01:15 web1 Mailman cgi-wrapper (admin): Operation not permitted

I've tried stracing Apache process to see where it might get permission issues, but I don't see anything like it.

Does anyone have a clue how to fix it?
