Bug#435993: htdig: crontest failure lockfile-create: command not found
it seems that htdig cron files are giving output when the package itself is removed
(REMOVE) or its dependencies (AUTOREMOVE).
log available at:
AUTOREMOVE CRON.DAILY  ['/etc/cron.daily/htdig: line 3: lockfile-create: command not found\n']
you should check that lockfile-create is there
