OCamlfind build fails

When I try to install ocamlfind using opam install ocamlfind, compilation fails and gives this message:

According to past Stack Overflow answers, this install fails sometimes if m4 is not installed, but I have m4 installed and in my path so that's not the problem.

Looks like a problem in your system or in a package manager. First, I would suggest not to use system compiler, but make a new compiler installation from scratch:

opam switch install 4.02.1
eval `opam config env`

If this doesn't work the try to look at your compiler toolkit, and ensure that linker is from the same toolkit as a compiler (at best, all tools, should link to the default OS X toolkit)
