Unable to build irmin-redis for irmin1.4.0 trunk version.

[ssdubey]

I am trying to build the Irmin-redis backend for Irmin 1.4.0 trunk version. It is failing with an error

ocamlc src/.irmin_redis.objs/byte/irmin_redis.{cmi,cmti} (exit 2)
(cd _build/default && /home/opam/.opam/4.07/bin/ocamlc.opt -w -40 -g -bin-annot -I src/.irmin_redis.objs/byte -I /home/opam/.opam/4.07/lib/astring -I /home/opam/.opam/4.07/lib/b$
File "src/irmin_redis.mli", line 12, characters 11-25:
Error: Unbound module type Irmin.AO_MAKER
Hint: Did you mean KV_MAKER or S_MAKER?

It seems AO_MAKER is modified in src/irmin/irmin.mli

Yeah, sorry about that - AO_MAKER and a bunch of other stuff have been renamed/removed in the latest revision. I will make sure to update this next week.
