I saw that you are using XCode 2.5. If you want to target 10.2 I think  
you need to explicitly tell the XCode installer that you want to add  
10.2 support. So you could try and reinstall and do a custom install.  
If you just want to support 10.3 then you need to change the  
SDKROOT_ppc setting in your project build settings. I'm using XCode 3  
but I don't think the instructions have changed. Do the following:

1) Open Project Info using the Project -> Edit Project Settings menu  
item.
2) In the window that appears select the configuration you want to  
edit. I selected Release.
3) Click on the Build tab.
4) Scroll to the bottom of the settings and find "User-Defined". This  
is the last section in the list for the project I'm looking at.
5) You should seek SDK_ROOT_ppc defined as /Developer/SDKs/ 
MacOSX10.2.8.sdk. Just change it to /Developer/SDKs/MacOSX10.3.9.sdk.

Hopefully that will work for you.
