Problem running procmail by cron

Hello procmail users,

I apologize first for troubles i generated trying to get informations
on my problem, sending by mistake requests to the mailing list ...

I use procmail since some days, and the SHELL script given
in PROCMAIL(1) man pages for postprocessing a mailbox.

Scheduled by cron on under SOLARIS 2.4  i get error messages with
command : formail -s procmail
... 
procmail: procmail: cannot open
procmail: procmail: cannot open
procmail: procmail: cannot open
...


Running into C-shell it is OK. 
I check the PATH in the script; I seems OK.

Have you any idea ?

Thanks,

Bernard RAOUL.
