dump mksnap_ffs: not found

[D.Pageau]

I have this error when I try to run dump from cron where dump didn't 
find mksnap_ffs.  I have try to add "set path = /sbin" to dump script 
without success.

Any suggestions?

mksnap_ffs: not found
dump: Cannot create /var/.snap/dump_snapshot: No such file or directory
