py2app does not cause additional compilation. As long as the python  
framework and all extensions and shared libraries  are build for 10.4  
the resulting .app should work just fine.

In theory it should even be possible to build extensions on 10.5, as  
long as the python framework is build with the 10.4u SDK and  
MACOSX_DEPLOYMENT_TARGET is set to 10.4. That's not something I've  
tested though, just compiling all C/C++ code on a 10.4 system is  
therefore the safest course.
