Re: beta OPAM instructions

The CFLAGS for the runtime can be tweaked to cross-compile to 64-bit, but
the OCaml compiler doesnt quite support this yet.  So you'll need to stick
to a 64-bit host for the moment.

It should be possible to cross-compile with some OPAM switch trickery in
the future though...
