why not set this option when you call cmake? so: cmake -DCMAKE_OSX_ARCHITECTURES=386 path-to-source on your 10.6 system and cmake -DCMAKE_OSX_ARCHITECTURES=ppc path-to-source on your old system (that is, if you use the command line cmake). Alternatively you could add the -m32 option to gcc like this export CC="gcc -m32" cmake path-to-source on your 10.6 system where a 32 bit application should then be build (according e.g. http://www.cyberciti.biz/tips/compile-32bit-application-using-gcc-64-bit-linux.html , which should also be true for Mac OS X 10.6).
