Read 'man su'. I dont really understand this stuff well enough, but a 'login shell', that is, one started by /bin/login, is setup with a different environment to a shell that's started by su (or by, say, cron). This is why a shell command or script may work for you when you're logged in, but not if you run it from cron. I'm sure other's can explain it more correctly and fully.
