You should be more pleased by this version. There are a lot of build
files, and no install command. So, I provided mine, which seems to
work, but I don't know what files should be installed. I bet on:

- .a, for the native code;
- .cma, for the ocaml bytecode;
- .cmi, for the interface;
- .cmxa for the ocaml native code;
- .cmxs for the plugins;
- .cmx if the compiler wants to inline code.

What do you think?
