Firstly. There is never ever a reason to use "for" when dealing with an open-ended list.
Secondly. Convoluted one-liners should be formatted scripts.

Quote:
for messages in `cat syslog_message_list.txt`; do grep $messages syslog.`date +%d%m%y`.log | tr -s " " | cut -d" " -f4,9- | sort| uniq -c >> syslog.`date +%d%m%y`.report; done

This "while" construct easier to read when properly laid out and does not include the risk of a "for" line becoming too long or not dealing with space characters correctly:

Code:
cat syslog_message_list.txt | while read messages
do
       grep "${messages}" syslog.`date +%d%m%y`.log | \
       tr -s " " | \
       cut -d" " -f4,9- | \
       sort| \
       uniq -c >> syslog.`date +%d%m%y`.report
done

Thirdly. Don't run convoluted on-liners from cron. Run a script containing appropriate environment settings - especially the Shell shebang and of course a correct $PATH which includes a path to Pearl.
