An easier way to do this under Linux is:

0-59/5 * * * * /apps/mrtg-2.8.8/mrtgsched

Check /var/log/cron to see what might be going on with your entries.

The script itself specifies all config files and binaries by their fully qualified paths so I don't think it's a path related issue. Besides, there isn't any mail being sent to the mrtg user - I understand cron would send a mail if it has problems running the file.
