yes that's true, but in the info (step 3 and 4) it is mentioned that you need to create xorg.conf
also nvidia-xconfig creates xorg.conf if it does not exist but in this case ps and pkg-config called, printing a message like "busybox ps invalid option ... pkg-config not found ..."
if it really worths adding pkg-config and procps to dep list i am ok with it ? maybe best is to add this to info file ?
