This is baffling.  Was there anything to stderr?  The MLB
"$(SML_LIB)/basis/unsafe.mlb" is referenced in
mlton/front-end/sources.mlb.  Either it should appear in an error
message indicating it can't be found, or, the files that it causes to
be included should appear.  If you look at
build/lib/sml/basis/unsafe.mlb, you will see a reference to structure
Unsafe, and tracing through the MLBs, I would expect to see the files

  build/lib/sml/basis/sml-nj/unsafe.sig
  build/lib/sml/basis/sml-nj/unsafe.sml

If those don't appear then there us no way Unsafe should be defined.

We need more to go on.  Can you please send the complete log of a
clean svn checkout and (failed) build, as well as the complete stdout
and stderr of the above command Matthew had you run.  Thanks.

I don't see how this could matter, since you are failing in the second
round bootstrap.
