This is likely a missing js_of_ocaml constraint. Could you please try something like 

opam install js_of_ocaml.2.6 vg

That fails in the same way.

https://github.com/ocsigen/js_of_ocaml/blob/b92d73489c05d8616d4defb9ee0d421d2da01c52/Makefile.conf#L62

This suggests that the ppx is not available for ocaml < 4.02.2.

Thanks for the analysis. I constrained on master and submitted a PR to the OPAM repository.
