See the second and third paragraphs under the third bullet of Possible
Errors on that page.

You can't build mlton from source without first installing a binary
version.  You should first go to
  http://mlton.org/Download
and download the Darwin package.  Simply untar it in / as root.  That will
install /usr/bin/mlton, /usr/bin/mllex, /usr/bin/mlyacc, etc.

As you noted before, if the gmp library is not in /usr/local/lib,
then you will need to adjust
  /usr/lib/mlton/include/platform/darwin.h
and you may also need to edit
  /usr/bin/mlton
and edit the -target-link-opt darwin line to read:
        -target-link-opt darwin '-L /path/to/gmp -lgmp'         \

At this point, you should have a working MLton installed, and, if you
wished, you could now continue with a self-compile.  But, there is really
no need.

The meaning of the line:

    You need to have {{{mlton}}} in your path to build MLton from source.

is that the executable mlton must be on your path.  Note that with
non-text web-browser, {{{mlton}}} is displayed in a typewriter font, which
is meant to indicate that we are speaking about a particular program, not
a particular path.
