Since you are on OS X 10.7.5, I don't think you need to do this at all. The instructions mention the requirement is for OS X "up to version 10.2.8". I install OCaml on Mac all the time without changing this setting. Currently I have:

$ ulimit -s
8192

in the README document,

can not connected directly.

In the INSTALL document,
"* Under MacOS X up to version 10.2.8, you must raise the limit on the
  stack size with one of the following commands:

    limit stacksize 64M  # if your shell is zsh or tcsh
    ulimit -s 65536      # if your shell is bash     "

But
ulimt -s 65536 yield
"ulimit: stack size: cannot modify limit: Invalid argument"

I change the value 65536 to 65532
   ulimit -s 65532
and 65532 is recognized the maximum number on Macintosh 10.7.5 (Macbook pro
and iMAC).

Are there any differences on the Macintosh OS version or Machine type?

Best Regards.
