Here's how I got it to work. I created my CC package and told it to "ignore conflicts and continue installations", I also told it to install to the default application directory. Both of these are in the custom settings of course. I then manually copied the entire package folder that CCP generates to the users application folder via Apple Remote Desktop. Once there, I ran a Unix script as 'root' with the following input:
cd applications
sudo installer -pkg /Applications/Graphics_mac/Build/Graphics_mac_Install.pkg -target /
It installed on pretty much every machine, but I did run into an issue on one or two machines which i attributed to an out-of-date ARD client settings. Hope that helps!
