Comment 1 for bug 741703

We've just verified that objinfo is not even compiled by default, let alone installed with a particular name, at least in OCaml 3.11.2.

This is how to install the utility if you have installed ocaml from sources:

From the ocaml source directory it can be made with
  make -C tools/ objinfo

And then installed (as root) with:
  cp tools/objinfo /usr/local/bin/ocamlobjinfo
