The commands are exceuted from some script inside the pnd.
I did try the pnd tool to extract the pnd, and then I located the .sh file and changed gksudo to gksu, and saved the pnd again.
But the next line after the gksu is a line starting with sudo, and now the log shows that it fail there as well.
Here is the log after running the modified pnd, followed by the run_gingerbread.sh script from within the pnd (edited version):
