Well, let me rephrase that....  I don't want to install Xcode 3.0 if I 
don't have to...  :)

Hmmm, looking at the code:

cmGlobalXcodeGenerator.cxx line 2645:

  if(this->XcodeVersion >= 32)
       {
       osxArch = "$(ARCHS_STANDARD_32_64_BIT)";
       }
   else if(this->XcodeVersion <= 25)
       {
#ifdef __i386
       osxArch = "i386";
#endif
#ifdef __ppc__
       osxArch = "ppc";
#endif
       }
     else
       {
       osxArch = "$(ARCHS_STANDARD_32_BIT)";
       }


I bet 30 had the ARCHS_STANDARD_32_64_BIT.  So, James, can you try 
changing CMake to have  if(this->XcodeVersion >= 30) and see if it fixes 
the problem?
