Doing just that right now. Needed install is automake and autoconf and
all their friends from MacPorts, because the system delivered automake
is too old. At least that's the message I got. And it needs to rebuild
the configure and friends at least on my machine (Snow Leopard and
MacPorts latest version).

What I did to get it running was the following:

PATH=/opt/local/bin/:$PATH aclocal
PATH=/opt/local/bin/:$PATH autoconf
PATH=/opt/local/bin/:$PATH ./configure
PATH=/opt/local/bin/:$PATH make
PATH=/opt/local/bin/:$PATH make install

If you have a default install of MacPorts, you might not need the PATH
stuff and can just run aclocal and autoconf - I usually have
/opt/local/bin at the end of my $PATH so default is still using system
delivered tools and only when explicitely required does it use
MacPorts tools.

I really hate the mlton step, it takes my poor old macbook pro quite
down, resource-wise ;)

Compiles fine and installs fine, demo hello world does run fine, too.
Looks like that cuts it. Only error I still got was on the make
install step when at the end you call ldconfig - that's not there on
the Mac, it's only needed on Linux.

Oh, regarding the question someone asked a bit ago: it is
platform/darwin.h of the mlton installation that needs the #define
_XOPEN_SOURCE added so the generated C code does compile - otherwise
the C compiler step will complain about the depricated ucontext calls.
I just installed the binary install of mlton and patched the
platform/darwin.h header right before the include for ucontext.h:

#include <termios.h>
#define _XOPEN_SOURCE /* needed for ucontext functions, as those are
deprecated */
#include <ucontext.h>
#include <utime.h>


bye, Georg
