Even a weekly launchd job (user agent) will generate a lot of spam--I 
did it to myself.  A long time ago, I created and loaded a simple 
test job to try to understand the launchd parameters better.  When 
done, I _thought_ I unloaded it and deleted everything.  Some time 
later, I noticed the following line being repeated in the system log 
every minute:

14-03-19 8:10:27 PM	org.ctreleaven.testjunk2[1856]	Ignore me 
(~/OptimizeMythDB/testjunk2.sh)

I've tried various incantations with launchd to get it to shut up but 
the best I can do is remove it for the current login session (with 
'launchd remove org.ctreleaven.testjunk2').  Next login, it's back. 
It doesn't really hurt anything; it just bugs me.

I suppose for the case I've outlined, we would just tell the user to 
re-install MacPorts and then uninstall it properly to rid them of 
such a zombie.
