For starters, you don't have any environment variables assigned at the
top of your crontab.  Here is mine:

# Establish environment variables.
JAVA_HOME='/etc/java-config-2/current-system-vm'
PATH='/home/dwn/bin:/usr/local/bin:/bin:/usr/bin:/etc/java-config-2/current-system-vm/bin:/etc/java-config-2/current-system-vm/jre/bin:/opt/bin'
TMPDIR='/tmp'
HOME='/home/dwn'
SHELL='/bin/zsh'
LOGNAME='dwn'
LC_ALL='en_GB.UTF-8'
http_proxy='http://localhost:8080'
ftp_proxy='http://localhost:8080'
RSYNC_PROXY='localhost:8080'
ZFTP_PREFS='P'
PGHOST=''
PGPORT=''
