Which Xcode version do you have installed on the iMac? And why are you  
compiling on a 10.3.9 machine? (although it should still work) You can  
very easily cross-compile a program for another Mac OS X version on  
Mac OS X: http://wiki.freepascal.org/OS_X_Programming_Tips#Compiling_under_10.5_for_10.4_and_below 
  (have a look under /Developer/SDKs to see the names of other SDKs,  
and note that the 10.3.9 SDK is not installed by default by Xcode 3.x,  
so you may have to run the installer again and explicitly mark its  
checkbox).

This cannot be explained without going into detail about how linkers  
work, and the specifics of the PowerPC architecture. I don't have time  
for that right now.

What does "would not install correctly" mean? Please, always mention  
the specifics.

That problem should have been fixed in 2.2.2: http://bugs.freepascal.org/view.php?id=10541

I'm not sure why you would nevertheless get such errors, unless you  
are trying to compile using DWARF debug information (which was not yet  
properly supported by Xcode 1.5).
