Great stuff! I have a FreeBSD 9 VM that I am installing all this on at the
moment.  I ran into this after cloning the repo fresh:

~/mirage-kfreebsd/packages/mirage-stdlib/src$ make
gmake -f GNUMakefile PREFIX=/usr/local all
ocamlrun ocamlc -strict-sequence -g -warn-error A -nostdlib `./Compflags 
pervasives.cmo` -c pervasives.ml
Fatal error: the file ocamlc is not a bytecode executable file
gmake: *** [pervasives.cmo] Error 2

Why are you running "ocamlrun ocamlc"?  The bytecode binaries are
compiled in with a copy of the bytecode interpreter, so you can just
invoke them directly as "ocamlc".  Better still, use the native
version of "ocamlc.opt" which will give you much faster compilation.

I applied this to continue the compilation, but I guess this is
because you have a custom version of ocaml installed, I'm guessing?
