It is the only way to get a build that works with PPC systems, with some care you can binaries on 10.7 that work just fine earlier releases. To create binaries that work on 10.5 (or even 10.4) you'll need a new python install though, the Intel-only installer on python.org only supports 10.6 or later due to the Tkinter dependency. The hardest part w.r.t. binaries that run on earlier versions is that C software that uses a configure script might detect features on your build system that aren't available on earlier releases.
