Problem with macports install, any help greatly appreciated

[John Essam]

Dear All,

I have recently installed macports on my mac book pro Mac OX platform  
10.5.8 to run the Gimp software as recommend by Gimp. I must admit I  
am not that much of a techie and I have found the whole process a bit  
bewildering. Eg I have never used the terminal before, not even  
certain which terminal to use, I think it's the installed with my OX  
platform.

Heres what I have downloaded so far

X11		version 		2.1.6	installed under aplications/utilities

Xcode	version		3		installed in developer folder


Macports					installed yesterday, so I gues it must be the lateast  
version

When I type into the mac terminal -tcish-80x24 	


sudo port install gimp as instructed on the gimp web site this is what  
I get.

when I tried to download the latest version of Xcode from the mac web  
site it won't let me download it as I don't have the 10.6 platform

Any help with this would be greatly appreciated, as at the moment I  
don't really have a clue as to what to do, and am completely out of my  
depth.


Kind Regards
