Crontab install

Step 4 of the INSTALL.txt file walks you through the "Install your crontab (UNIX ONLY)" process. After I made the necessary edits each of the non-commented lines got rejected by crontab for invalid/unexpected characters.
After a fair bit of time trying to get the crontab commands loaded, I elected to bypass this step so I could proceed with getting elgg up and running. I planned to come back to cron later and manually enter the cron commands. However, what's interesting is that there was no "/pg/cron/" directory in my download tar file.
Not sure if I have what I need for the cron jobs to even work.
