This is not actually true. You can compile for ppc with gcc-3.3 and for
intel with gcc-4.0 and then lipo the results together. I believe that
there are xcode settings to do all this for you (but I don't actually
use xcode all that much...)
I am not aware of any differences in dlsym() behavior on intel and ppc.
