Are you quite sure about the necessity of this step? If you are starting
from a fresh Ubuntu, there is no /usr/local/lib/ocaml, much less
a /usr/local/lib/ocaml/3.12.1. I guess that you created this directory as
root on your distribution, but ?from the fact that you are installing the
OCaml packages? you do not seem to want to use it to build Frama-C. Unless
you are compiling Frama-C with a compiler that you compiled and installed
locally, but in this case, installing the distribution's OCaml packages
is asking for trouble, and creating this kind of link even more so.

Anyway, Zarith is a nice-to-have, but it does not bring any extra
functionality. It makes some analyses take less memory and time. If you are
not going to spend more than five hours in total waiting on Frama-C, you
can completely omit it.
