PATH braincramp

[Tim Kellers]

I'm having a tussle with one of those things I've done a zillion times, 
but now I can't fathom what the heck is wrong.

When I run flexbackup from a cron job (as root) , the following error is 
returned by e-mail to root:

Errors:
 mbuffer not found in $PATH
 dump not found in $PATH
 restore not found in $PATH

$PATH is set in root's  crontab: $PATH = "/sbin /bin /usr/sbin /usr/bin 
/usr/games /usr/local/sbin /usr/local/bin"

mbuffer is in /usr/local/bin and dump and restore are in /sbin

The cron'd command is: /usr/local/bin/perl /usr/local/bin/flexbackup 
-set backup -level incremental  

The machine is: Dell 2850 7.1-PRERELEASE FreeBSD 7.1-PRERELEASE #0: Sat 
Dec 27 03:44:52 EST 2008 amd64

When I run the command from Webin's interface for scheduled cron jobs, 
the command completes successfully

I know I'm missing something stupid, and I'm willing to wear the pointy 
hat if someone can enlighten me, somehow.
