Unable to make 10.6 Vanilla image

Need a little help getting past this error message below: [code]ssfhce005-l:InstaUp2Date mmadmin$ sudo ./instaUp2Date.py -p 10.6_vanilla Parsing the catalog files for 10.6_vanilla AirPort Utility 5.5.3 Remote Desktop Client 3.5.1 iLife Support 9.0.4 Mac OS X 10.6.8 Combo Update v1.1 iTunes 10.5.2 Java For Mac OS X 10.6 Update 6 Safari 5.1.2 Security Update 2011-006 Finding and validating the sources for 10.6_vanilla AirPort Utility 5.5.3 - downloaded and verified 10.3 Megabytes in 20 seconds (629.4 Kilobytes/sec) Remote Desktop Client 3.5.1 - downloaded and verified 3.7 Megabytes in 10 seconds (474.2 Kilobytes/sec) iLife Support 9.0.4 - downloaded and verified 67.1 Megabytes in 1 minute 36 seconds (735.9 Kilobytes/sec) Mac OS X 10.6.8 Combo Update v1.1 - downloaded and verified 1.0 Gigabytes in 40 minutes 8 seconds (441.2 Kilobytes/sec) iTunes 10.5.2 - downloaded and verified 102.0 Megabytes in 2 minutes 23 seconds (734.9 Kilobytes/sec) Java For Mac OS X 10.6 Update 6 - downloaded and verified 75.8 Megabytes in 1 minute 36 seconds (829.4 Kilobytes/sec) Safari 5.1.2 - downloaded and verified 47.1 Megabytes in 55 seconds (879.6 Kilobytes/sec) Security Update 2011-006 - downloaded and verified 136.3 Megabytes in 3 minutes 17 seconds (720.1 Kilobytes/sec) Finding the Installer disc for 10.6_vanilla Traceback (most recent call last): File "./instaUp2Date.py", line 716, in main() File "./instaUp2Date.py", line 678, in main foundInstallerDiscs = findInstallerDisc.findInstallerDisc(allowedBuilds=thisController.installerDiscBuilds) File "/Users/mmadmin/Desktop/instadmg/AddOns/InstaUp2Date/Resources/findInstallerDisc.py", line 201, in findInstallerDisc raise commonExceptions.FileNotFoundException('Unable to find OS Installer disc in any provided folder: %s%s' % (str(searchItems), folderString)) Resources.commonExceptions.FileNotFoundException: Unable to find OS Installer disc in any provided folder: ['/Users/mmadmin/Desktop/instadmg/InstallerFiles/InstallerDiscs', '/Users/mmadmin/Desktop/instadmg/InstallerFiles/BaseOS'] (['.svn', 'MacOS X Client 10.6 10A432.dmg'], ['.svn']) ssfhce005-l:InstaUp2Date mmadmin$ [/code] So I put the retail 10.6 disc in, it ran the command to import and generate the disc image fine as I see it sitting in the "BaseOS" folder now. But running the next step of building the Vanilla image gets me nowhere. It seems to be looking in the right place and the base image file is definitely there.
