Here is my current \_oasis file: 

```
OASISFormat: 0.3
Name:        testing syntax
Version:     0.1
Synopsis:    testing
Authors:     Johnathan Doeman
License:     GPL-3

Executable testmain
  Path:       ./
  BuildTools: ocamlbuild
  BuildDepends: batteries, deriving-ocsigen, deriving-ocsigen.syntax
  MainIs:     main.ml

```

Note that ocsigen-deriving seems to be properly installed on my system. I am able to use it in the toplevel after the correct #requires. I'm also using oasis version 0.3.
