GTK Warning

[Steve Slade <animaniaman earthlink net>]

Hello,

I'm very new to the world of UNIX having been introduced through my 
recent purchase of OS X. I am trying to find alternatives to programs 
such as Photoshop and Dreamweaver. I found the Gimp and Bluefish. I 
downloaded Fink and began installing GTK, Gimp, and Bluefish.

I loaded the fourth CD Xcode Tools that came with Panther (OS X 10.3). 
I installed GTK from source through Finkcommander (I still am tied to 
GUI's) and then installed the other two programs in the same way.

When I try to launch Gimp or Bluefish from a terminal window, I get 
this error:
	GTK-Warning **: Cannot open display: :0.0

I have no idea what that means and no idea what to do now. I apologize 
if this has been asked before. I will search the archives as time 
permits as I know they contain a wealth of information. I do have a 
project that I need to complete soon which is why I'm asking the list.

Any help is greatly appreciated. Thank  you.

Steve
