[rancid] "sh: clogin: command not found" when run from cron

[Chris Hunt]

Hello All,
    I'm having some trouble getting rancid to work properly after
migrating to CentOS 5.8.  I can successfully run it from the BASH while
logged in as the rancid user:
!
[rancid at noc ~]$ clogin -c 'show version' router-2.example.com
router-2.example.com
spawn ssh -c 3des -x -l nocservices router-2.example.com
 ...

But when run from the rancid user' crontab, it fails saying "The
following routers have not been successfully contacted for more than 4
hours." then lists the router.  The logfile shows:
sh: clogin: command not found
!

I suspected a path issue, so I added the path to the crontab file:

#
PATH=/usr/kerberos/bin:/usr/local/bin:/bin:/usr/bin:/var/rancid:/usr/local/rancid/bin:/usr/libexec/rancid:.
SHELL=/bin/bash
*/5 * * * * rancid-run -m me at example.com
#

Can someone please hit me with a clue bat?

Cheers,
