Snow Leopard's Ruby:

$ file /usr/bin/ruby
/usr/bin/ruby: Mach-O universal binary with 3 architectures
/usr/bin/ruby (for architecture x86_64):	Mach-O 64-bit executable x86_64
/usr/bin/ruby (for architecture i386):	Mach-O executable i386
/usr/bin/ruby (for architecture ppc7400):	Mach-O executable ppc

Here's RMagick2.bundle when built using Snow Leopard's Ruby 1.8.7:

$ file RMagick2.bundle
RMagick2.bundle: Mach-O universal binary with 2 architectures
RMagick2.bundle (for architecture i386):	Mach-O bundle i386
RMagick2.bundle (for architecture x86_64):	Mach-O 64-bit bundle x86_64

And ImageMagick:

$ file libMagickCore.dylib
libMagickCore.dylib: Mach-O 64-bit dynamically linked shared library  
x86_64
