On my intel-based macs I'll easily just stick w/fink or macports!

Testing has shown that, with the current state of optimization that the Intel processors are doing, it doesn't make sense to compile for your specific post-586 flavor; some tests showed that it was faster to use a generic i686 binary than it was to compile a tuned one for your processor. (But of course I have no idea if that's true on G4 or G5s - probably not.) Debian apt can compile packages, but generally just gets the binary from the repository.
