'which' doesn't work if the executable is not in your PATH 
environment variable.  Most flavors of cron (wisely) provide a very 
limited value for PATH, in some cases just "/bin:/usr/bin" and on 
some systems /bin is just a symlink to /usr/bin anyway...

If you are using Vixie Cron or a workalike, you can set PATH in your 
crontab and never have to worry about forgetting to use a full 
pathname. That can also help protect against running an unexpected 
version of something on a system where alternative implementations 
may lurk behind unexpected PATH's.
