What is wrong with my catalog file line

I'm trying to add adobe reader to my image. But the script says there is an error with the line. I had to comment it out in order to get the image to build. What did I do wrong? I used the checksum.py script on my instaUp2date install packages file and it worked for every other package there. Here is the line from checksums.txt # Adobe Reader X Installer Adobe Reader X Installer.pkg sha1:5f77fe82ec5266ddf825a8013ad0bb2a049ad740
