[Dirvish] curious problem - dirvish does nothing when run from cron

[scanner at apricot.com]

I just installed dirvish (all machines are freebsd 6 except for one
that is freebsd 5)

It all runs spiffily from the command line (using 'sudo' or from a
root shell via 'sudo su root' first)

However whenever it is run from cron it acts like a dry-run is being
done: ie: no actions are taken.

I have not delved in to the scripts yet, I was hoping someone here
could point out the stupid thing I was doing that caused it to behave
like this.

The biggest hint is the output from cron looks like:

04:30:01 dirvish --vault kamidake-root --image-time "23:59"
04:30:01 dirvish --vault kamidake-usr-local --image-time "23:59"
04:30:01 dirvish --vault old-kamidake-root --image-time "23:59"
04:30:01 dirvish --vault old-kamidake-usr-local --image-time "23:59"
04:30:01 dirvish --vault azaka-root --image-time "23:59"
04:30:01 dirvish --vault azaka-usr-local --image-time "23:59"
04:30:01 dirvish --vault matsubue-root --image-time "23:59"
04:30:01 dirvish --vault matsubue-usr-local --image-time "23:59"
04:30:01 dirvish --vault motoko-root --image-time "23:59"
04:30:01 dirvish --vault motoko-usr-local --image-time "23:59"
04:30:01 dirvish --vault fatora-root --image-time "23:59"
04:30:01 dirvish --vault fatora-usr-local --image-time "23:59"
04:30:01 dirvish --vault fatora-var-log --image-time "23:59"
04:30:01 dirvish --vault lockers00 --image-time "23:59"
04:30:01 dirvish --vault lockers01 --image-time "23:59"
04:30:01 dirvish --vault lockers02 --image-time "23:59"
04:30:01 dirvish --vault lockers03 --image-time "23:59"
04:30:01 dirvish --vault homes00 --image-time "23:59"
04:30:01 dirvish --vault homes01 --image-time "23:59"
04:30:01 dirvish --vault homes02 --image-time "23:59"
04:30:01 done

Note, all the jobs take no timme to finish. There is no new image
directory in each of the vaults. If I then run dirvish from a command
line via sudo it looks like:

07:51:59 dirvish --vault kamidake-root --image-time "23:59"
07:52:00 dirvish --vault kamidake-usr-local --image-time "23:59"
07:52:18 dirvish --vault old-kamidake-root --image-time "23:59"
07:52:20 dirvish --vault old-kamidake-usr-local --image-time "23:59"
07:52:47 dirvish --vault azaka-root --image-time "23:59"
07:52:48 dirvish --vault azaka-usr-local --image-time "23:59"
07:52:50 dirvish --vault matsubue-root --image-time "23:59"
07:52:51 dirvish --vault matsubue-usr-local --image-time "23:59"
07:53:00 dirvish --vault motoko-root --image-time "23:59"
07:53:02 dirvish --vault motoko-usr-local --image-time "23:59"
07:53:03 dirvish --vault fatora-root --image-time "23:59"
07:53:05 dirvish --vault fatora-usr-local --image-time "23:59"
07:53:06 dirvish --vault fatora-var-log --image-time "23:59"
07:53:12 dirvish --vault lockers00 --image-time "23:59"
07:53:19 dirvish --vault lockers01 --image-time "23:59"
07:53:35 dirvish --vault lockers02 --image-time "23:59"
07:53:47 dirvish --vault lockers03 --image-time "23:59"
07:54:27 dirvish --vault homes00 --image-time "23:59"
07:59:21 dirvish --vault homes01 --image-time "23:59"
08:00:45 dirvish --vault homes02 --image-time "23:59"
08:01:41 done

(notices it actually took time to do all these runs, and the new image
dirs exist.)

The cron command is:

30 4 * * *      /usr/local/sbin/dirvish-expire --config /usr/local/etc/dirvish/master.conf ; /usr/local/sbin/dirvish-runall --config /usr/local/etc/dirvish/master.conf | mail -s "Dirvish output" scanner

I put the explicit "--config" in there just to be sure it was getting
the right config (which by default on freebsd ports installs is
/usr/local/etc/dirvish/master.conf.)

Any immediate ideas?
