jbuilder broken for OSX for OCaml 4.06.1?

[nikgraf]

I'm a Ocaml newbie and just tried my first steps with OPAM.

I ran

brew install opam
opam init
opam install c

That's the error I got:

opam install cmdliner
The following actions will be performed:
  - install result   1.3                                [required by cmdliner]
  - install topkg    0.9.1                              [required by cmdliner]
  - install cmdliner 1.0.2
===== 3 to install =====
Do you want to continue ? [Y/n] Y

Did I do something wrong?

I also tried downgrading to jbuilder.1.0+beta19.1 and then install cmdliner as well as running opam install opium. Both didn't work.

I realized that I didn't export opam config env
