IIRC Redhat had a special crondaemon named anacron (asyncronous cron)
which was able to find out when a cron-job was last executed and would
then execute it again if it was overdue. It looks like the
vcron/vixie-cron (as installed by gentoo) can do it as well, but I
didn't try.
OTOH, you can write a small script that does something like that:

====================================================================
if datediff(getdate(getfirstline(/var/log/lastrunof.cronjob)), now) \
   > 1 day then
   run cronjob
   echo now > /var/log/lastrunof.cronjob
end if
====================================================================

and execute it every 5 minutes. Thats just a bit of pseudocode, I don't
know if you can do that with shell-scripts (especially the datediff
thing) but perl would do that.
