cron is run with an extremely limited PATH environment, quite probably your script isn't finding commands its trying to run.
You might try something like
* * * * * . /etc/profile ; /path/to/script to get a more complete profile before running your script, or modify the script itself to set a more complete PATH value before you do anything else.
