InstaDMG 1.6b2 and 10.6.3

I’ve dl InstaDMG 1.6b2 and followed the steps listed in the pdf, but it errors out at the end when it tries to created the output fille. The steps I followed:

1. sudo ./instadmg/AddOns/InstaUp2Date/importDisk.py –automatic –legacy
2.sudo ./instadmg/AddOns/InstaUp2Date/instaUp2Date.py 10.6_vanilla –process

And at the very end here is what’s in the log file:
