caml_gr_unset_cursor (and others) is defined in src/grY11.c in advi. You
have to make a .so (e.g. dlladvi.so) out of the C stubs (src/*.c). This
can be done with ocamlmklib. You can then install it in the standard
location (/usr/lib/ocaml/stublibs currently) and the pure bytecode
executable should be able to run with plain ocamlrun.


Hope this helps,
