[CakeML] cakeML build fails

I've downloaded cakeML from git and have been building it. I was warned
that I needed 16 GB to do everything, so I expected failure. But I wanted
to see how far it got before crashing. Here's the error message:

1. Is this the expected place of failure? (This is on an 8 GB box running
2. I just invoked "make" in the top level. What is the invocation if I
wanted to avoid
the memory-expensive bootstrap?
2a. The build needs lem. This should be mentioned.
2b. In lem, the hol-lib directory has a spurious file called
derails the build. I've talked to Scott about this already.
3. I would like to explore the verification aspects of the system. In
I want to define (executable) functions in HOL and prove properties,
map the functions to cakeML and get some sort of
theorem out that I can use to make a formal connection between the
function, and the executable code.
For example, I define factorial and prove that it is always positive:
val fact_def = Define `fact n = if n <= 0 then 1 else n * fact (n-1)`;
(* The fact function could be over integers, if need be. *)
val fact_pos = prove(``!n. 0 < fact n``, ....);
... and now what steps do I take? I have read the relevant papers by
others, but now I am seeking more concrete hints.
