Why does building ocaml-bin-prot using MacPorts fail?

Question

I am trying to learn Ocaml using Real World Ocaml. I installed ocaml using MacPorts. Now, I am trying to install ocaml-core-extended:

$ sudo port install ocaml-core-extended

but it fails while installing dependency ocaml-bin-prot:

Here is the relevant part from the build log:

I looked at the lib/type_class.mli and I have no clue why there would be a syntax error there. It is just a macro expansion. I would like my bug report to be a little better than "here's a problem".

So, has anyone encountered this failure? Any hints?

Answer 1

I am assuming the specific problems I had are more related to the transition to Mavericks than anything else.

In the mean time, I decided to install opam with ocamlbrew, and everything worked very smoothly.

I was able to set up my environment following the instructions.

Answer 2

What is the version of core library? Looks like the library is not updated for OCaml 4.01, probably the port is old and haven't catched up yet..
