Cannot install with opam (jbuilder-related?)

I'm on this commit currently:

    Merge pull request #133 from avsm/jbuild
    
    port to jbuilder

When I do:

~/ocaml/ocaml-cstruct$ opam pin add cstruct file://$(pwd)

I get the following error:

You've pinned an older version of a cstruct opam file to the development version of the tree, but seem to be using the wrong opam file.

If you do opam pin add cstruct --dev does it work for you?

I am not sure what I am looking for. Is this what I am supposed to do?

opam pin add cstruct --dev file://$(pwd)

Below is the capped output:

As mentioned in #142 (comment) I do have a work-around, I was just wondering if this is a general problem or if my opam installation has deviated from the norm somehow.

Is this still a problem @cfcs?

[cfcs]

Nope! Everything builds fine now!
