 ruby is multi threaded, this mean that you don't need to use pthread.

 rb_require return Qtrue if the file was successfully loaded. If "test.rb"
 create a module, or a class you can call rb_const_get() to retrieve the
 VALUE associated with the module (class), otherwise use rb_cObject (if the
 function is at top level)

 Here you must use rb_thread_create(), and call `join'

 A little example :

pigeon% cat thr.c
#include <ruby.h>

static VALUE
thr_run(obj)
    VALUE obj;
{
    int i;
    for (i = 0; i < 2; i++) {
        rb_funcall(obj, rb_intern("test"), 0);
    }
    return Qnil;
}

int main()
{
    VALUE module, thread;
    ruby_init();
    rb_require("test");
    module = rb_const_get(rb_cObject, rb_intern("Test"));
    thread = rb_thread_create(thr_run, (void *)module);
    rb_funcall(thread, rb_intern("join"), 0);
    return 0;
}
pigeon% 

pigeon% cat test.rb
module Test
   def test()
      print "Hello\n"
   end
   module_function :test
end
pigeon% 

pigeon% thr
Hello
Hello
pigeon% 

 Look at mod_ruby.c, you have a more complete example.
