I do understand that this is an X aplication, I am trying to run it in 6.2_release using Xorg 7.2 and Gnome2, still giving me that strange error when I try to execute from the shell as root, I try google at it and nothing shows up for it. Any ideas what might be happening?

No DISPLAY variable set for root, which has its own environment.
Try this:

  log in to X as your normal user
  xhost +localhost
  su -
  setenv DISPLAY :0.0
