[erlang-questions] A simple NIF so: compiles on Ubuntu, but not on MacOSX. Is something missing?

Dear All
I'm writing a simple NIF. This is what I'm using to compile it:
gcc -Wall \
-I/usr/local/lib/erlang/usr/include \
-fPIC \
-shared \
-o simple_nif.so \
simple.c simple_nif.c
This compiles on Ubuntu, but trying it on a Mac I get this error:
> Undefined symbols:
> "_enif_make_badarg", referenced from:
> _get_params_nif in ccNKt95s.o
> "_enif_make_tuple_from_array", referenced from:
> _get_params_nif in ccNKt95s.o
> "_enif_make_int", referenced from:
> _get_params_nif in ccNKt95s.o
> "_enif_get_tuple", referenced from:
> _get_params_nif in ccNKt95s.o
> ld: symbol(s) not found
> collect2: ld returned 1 exit status
Both machines are running erlang 14B, installed from source (the -I path
is the same for both). I don't have my Ubuntu machine with me atm, but
this is what's in .../usr/include on the Mac:
> $ l /usr/local/lib/erlang/usr/include/
>
> driver_int.h
> erl_driver.h
> erl_drv_nif.h
> erl_fixed_size_int_types.h
> erl_int_sizes_config.h
> erl_memory_trace_parser.h
> erl_nif.h
> erl_nif_api_funcs.h
Is something missing? Does the Mac need extra arguments to compile?
With thanks and best wishes
Ivan
