This should be `install:` rather than `build:`; and `opam-version: "1"` is 
old. Please refer to
  http://opam.ocaml.org/doc/Manual.html#opam

for up-to-date documentation.
But that's not the issue that's causing the problem, Opam would still accept 
it.

Opam does copy the contents of files/ into the unpacked tarball directory, 
and runs all commands from there. A return code of 127 indicates that the 
shell didn't find the file to execute, though -- so I would guess something 
got mixed up in installing your new metadata:

- is the package pinned (which is the recommended way of testing) ? In this 
case, the metadata from the repo may be masked locally. See `opam show ocaml-
ios64 --where` to see the location of the metadata used by Opam.

- did you `opam update` ?

- if your repository is under version control, did you commit the new files ?

Hope this helps
