Thanks guys for your quick replies. I'm almost too embarrassed to say what the problem was, but for the sake of future idiots like myself...
If you log in to dreamhost and are party to multiple accounts, make sure you are in the right account.
Cause if your not in the right account, it's not going to find the file.
sdayman, your question of are you sure i'm running cron as the right user was right on the money!
(for the record, since you both asked: the error files did not say anything more than no input file found and the path.)
