A few things

Steve,
There are indeed a number of profound differences between x86 and PPC
binary formats and other issues surrounding software distributions. For
one thing, the processor architecture is greatly different, and
supporting library code is correspondingly so. For another thing, even
the way file-structures are addressed is different. On the x86, memory
is addressed in "little-endian" form (low-byte first, then upper) while
on PPC, it is addressed "big-endian" where the high-byte is first, then
the low. This means that you must run source code through a compiler
specifically coded to produce binary code for a particular hardware
processor before you achieve a downloadable product.
