Comment(by mike@…):

 Replying to [comment:14 ryandesign@…]:
 > When you say x86, you mean i386? The possible architectures in MacPorts
 are i386, x86_64, ppc, and ppc64.
 Yes, i386: although in practice that really means that the code suits
 processors that >= i486, and wouldn't work on the original 80386/80387.
 Since there aren't any macs that are < Pentium, it's a moot point that
 appeals only to avid readers of the Intel architecture manuals.

 > > If building on an x86-64 machine, the C components (i.e. the runtime
 system) need to be built in 32-bit.  It doesn't matter whether the OCaml
 components (i.e. the Oberon compiler) are built with the 32-bit or the
 64-bit OCaml compiler.  I don't know much about MacPorts, so I don't know
 how accurately you can specify that requirement.
 >
 > I believe we already specify that. We say "supported_archs i386 ppc"
 meaning that MacPorts will pass "-arch i386" (or "-arch ppc") in the
 CFLAGS, CXXFLAGS and LDFLAGS when building obc. MacPorts will enforce this
 architecture for all dependencies as well, except that we also write
 "depends_skip_archcheck ocaml" so that MacPorts does not attempt to
 enforce any particular architecture of ocaml.

 Sounds good to me.
