I managed to build a working version of SML/NJ 110.99.2 (released on
2021-09-22). The patch is included below (use `git am --scissors` to
apply).

Major caveats:
* This patch only deals with x86-64. For 32-bit, some changes need to be
  made:
  * Download "boot.x86-unix.tgz" instead of "boot.amd64-unix.tgz".
  * Patch "base/runtime/objs/mk.x86-linux" instead of
    "base/runtime/objs/mk.amd64-linux".
  * Invoke the install script using `-default 32` instead of `-default 64`.
* This does not install the SML/NJ library. I used the `-nolib` option
  to disable the building of the library. When I try to build without
  the `-nolib` option, the build always fails with this error:

----- start of snippet -----
/Users/jhr/Work/smlnj/sml-legacy/base/system/smlnj/installer.cm:29.7-29.32 Error: link-time exception in library code $smlnj/installer.cm@1570(installer/nix-install.sml)
  SysErr: No such file or directory [noent]<exec.c>


/tmp/guix-build-smlnj-110.99.2.drv-0/bin/sml: Fatal error -- Uncaught exception Link with 0
 raised at ../cm/compile/link.sml:357.28-357.35

FAILURE: unpacking failed
./config/install.sh: !!! Installation of libraries and programs failed.
command "./config/install.sh" "-default" "64" failed with status 1
----- end of snippet -----

  I don't know what this error means.

  Note that "jhr" is *not* my username. "jhr" appears to be the initials
  of John H. Reppy, one of the authors of SML/NJ.

  Surprisingly, when I keep the directory of the failed build (`guix
  build --keep-failed smlnj`), and then build inside the build directory
  by hand (i.e. `cd /tmp/guix-build-smlnj-110.99.2.drv-1 &&
  ./config/install.sh -default 64), all SML/NJ libraries are
  successfully built. I was not able to determine why the build fails in
  Guix but succeeds manually.


Credits:
* This patch is based on Brett Gilio's smlnj patches.
* I also looked at how smlnj is packaged in NixOS:
  * https://github.com/NixOS/nixpkgs/blob/21.05/pkgs/development/compilers/smlnj/default.nix

The error above occurs because the build process uses nix-install.sml,
and nix-install.sml uses `OS.Process.system` (in the `unpack` function).
`OS.Process.system` relies on /bin/sh, but /bin/sh is not present in the
Guix build environment. "No such file or directory" presumably refers to
the absence of /bin/sh.

Unfortunately, the fix might require some binary patching. /bin/sh is
hardcoded in sml.boot.amd64-unix/SMLNJ-BASIS/.cm/amd64-unix/basis-common.cm
(a binary file from boot.amd64-unix.tgz).

Linking [1] for our IRC discussion about this.

You proposed patching /bin/sh to /tmp/sh, and symlinking /tmp/sh
yourself, did that work?

If not, I can still write a SMLNJ binfile patcher if you feel the need
for it (literals should be pretty easy to patch, see
sml/gc/build-literals.c for their format).

Best,
Josslin Poiret

Yes, it did work. I managed to build smlnj (including libraries). Thank
you for helping on IRC. Here's the patch that uses the /tmp/sh method:
