Well, this got me thinking and I had to do some playing around to  
figure out what was wrong...

The difference was that I was testing the command by su-ing into the  
user, rather than logging in as that user. What I didn't know was su  
does not change your environment, only permissions (as far as I can  
tell)

So I was testing with my environment, but crontab was running under  
the other user's environment.

I always thought that su user and login user were equivalent. Now I  
know better :-)

Anyway, thanks for putting me on the right path.
