Mr. Korab,
  Thanks for the reply.  I had tried that, but apparently there are some
additional non-absolute calls within the code itself that were failing
due to a  misconfigured path.  As John Heasley helpfully pointed out,
there is yet another path variable in /etc/rancid/rancid.conf.  I copied
the path from the rancid user's crontab into rancid.conf and away it
went!  I can't believe how much time I spent on that before asking the
group...Many thanks to Mr. Heasley.  FIXED!

Cheers,
-Chris
