This doesn't seem so hard once we know how to build all this.

I just tried to redo this to see how it works

$ svn checkout http://hol-light.googlecode.com/svn/trunk/ hol_light
$ cd hol_light/Proofrecording/hol_light
$ make

and it failed with

[...]
convert type.ml ...
convert update_database.ml ...
convert wf.ml ...
warning: ignoring 'lemma1' in wf.ml
warning: ignoring 'pth' in wf.ml

         if test `ocamlc -version | cut -c3` = "0" ; \
         then cp pa_j_`ocamlc -version | cut -c1-4`.ml pa_j.ml ; \
         else cp pa_j_3.1x_`camlp5 -v 2>&1 | cut -f3 -d' ' | cut

                    else ocamlc -c -pp "camlp4r pa_extend.cmo

                    fi

Any hints?

Also, what is the HOL Light release policy? Is everybody really just 
using the svn head?
