Need more details - the program fails to execute or you're failing to get the results you want when it does execute?
$ ls -l `which xorgconfig xorgsetup`
-rwxr-xr-x 1 root bin 49016 2004-06-05 17:48 /usr/X11R6/bin/xorgconfig
-rwxr-xr-x 1 root bin 4666 2004-05-29 20:31 /usr/X11R6/bin/xorgsetup
That's where they should be and the perms they should have. If that isn't what you get, I guess you neglected to install X. Install those and try again. If you mean they run okay but don't produce usable results, post more details.
