With a recent upgrade of fcron, I ran into this problem (and solved it
by switching to absolute paths).  From fcron's changelog:

     * don't inherit fcron's environment when running a job but build
       the environment from scratch (cleaner, and this is what Vixie
       cron does)

I have no idea how the environment is built from scratch, but for me
anything run from the system crontab now has $PATH /usr/bin:/bin
