if you enter the "set" command in bash you get a list of bash
variables that are accessible to all programms that you execute. This
is called "the bash environment" (see [1] for more info). A lot of
programms really need to check the values of some of these variables
to execute. Cron has only a small portion of them set so a lot of
programms fail when run from cron (can't tell if this is your specific
case though)
