Apparently the R and your package have different architectures. The reason is most likely your package - often badly written Makevars or Makefile if some dependencies are used, or stale object files in the sources (failure to clean up) etc. You'd have to show us the package and exactly how you're trying to instal it if we are to help you further.

You understand the message incorrectly - it tells you the R (which is the one loading the package) cannot find binary of the same architecture in the package, but it can find another, different, architecture instead. "Snow Leopard" is not an architecture it's an operating system.
