[syslog-ng] log rotation

I've been trying to get logrotate to work on AIX and it simply doesn't "do" anything (run it with debug and it tells me its reading the config file then exits, files remain the same - regardless of size or age). So, what else should I try? Eventually it looks like I'm going to be feeding pipes and files for use with SEC - but I need to archive each log for 30 days, then archive all of those files for a year, etc..
