I don't know if this is right.  (The ref manual is a little unclear on what is 
the right way to do things.)  But I've done it this way.

-------------------------------
main.c
-------------------------------
#include <stdio.h>
#include <stdlib.h>
#include <libguile.h>

int main (int argc, char *argv[])
{
        SCM func_symbol;
        SCM func;
        
        scm_init_guile();
        
        // Load the scheme function definitions
        scm_c_primitive_load ("script.scm");  
        
        // Call func "do-hello" with 0 args
        func_symbol = scm_c_lookup("do-hello");
        func = scm_variable_ref(func_symbol);
        scm_call_0 (func);

        exit(EXIT_SUCCESS);
} 
-------------------------------
script.scm
-------------------------------
(define do-hello
 (lambda ()
   (display "Hello world.") 
    (newline)))
