Hi Christoph,

Since ocaml-lua is using oasis build system underneath the hood it is
possible to control configuration parameters via environment variables. Any
variable, if not set
explicitly by a command line, will be looked up in the environment.  In
your case enabling `luajit` should be as simple as:

     luajit=true opam install ocaml-lua

Regards,
Ivan
