lwt_react.ml field bind is required but not provided

[scottt]

Building lwt-2.4.5 fails when "--enable-react" is passed to configure

1. git checkout 2.4.5
2. ./configure --enable-react && make
   <...>
3. /usr/bin/ocamlfind ocamlc -c -g -I src/core -package react -I src/react -I src/core -o src/react/lwt_react.cmo src/react/lwt_react.ml
   File "src/react/lwt_react.ml", line 1:
   Error: The implementation src/react/lwt_react.ml
   does not match the interface src/react/lwt_react.cmi:
   ...
   In module S:
   The field `bind' is required but not provided
   Command exited with code 2.

I believe this is caused by commit bec7372

Try to update your react installation for a more recent version, it should solve this error.

@fccm, could you maintain a "known to work" react version in the lwt sources?

[fccm]

I'm not the upstream but you will find compatibility versions in the opam packages:
https://github.com/ocaml/opam-repository/blob/master/packages/lwt/lwt.2.4.4/opam
https://github.com/ocaml/opam-repository/blob/master/packages/lwt/lwt.2.4.5/opam

Indeed, this is solved by using React >= 1.0.0.

Lwt has since included an opam file in its distribution, so it should be easier to find the constraints.
