make the code compile

[HuStmpHrrr]

$ ocamlc --version
4.08.0

another problem I suffered a bit was the linking stuff:

_build/default/bin/kaleidoscope.exe: error while loading shared libraries: libbindings.so: cannot open shared object file: No such file or directory

I've got no idea how to fix it. It would be helpful if you can see whether this code is still working for you or not.
