Unlike pure Slackware, PAM is used in MOPSLinux, so my polkit was also
built with PAM support.
I tried to run pkexec:

aix@mac2:~$ pkexec manager2
Error executing command as another user: No authentication agent was found.

So it seems to work, but some components are still missing. Building
and installing polkit-kde-1 doesn't change anything.

Also, I tried to attach to process with gdb, and got this backtrace on segfault:

(gdb) continue
