actually, i'm setting the loadpath global myself:

VALUE load_path = rb_gv_get(":");
rb_funcall(load_path, rb_intern("push"), 1,  
rb_str_new2(my_resource_path));

not sure if it's the right way though... But I'm running rb_require  
and it finds the script just fine.

same as I'm doing it right now. The problem I'm having is with  
exception handling. Do I need to call ruby_sysinit()?

mmm... I'm sorry, I lost you here. What function are you calling with  
rb_funcall?

yes, I saw that (I always turn to the source when lost :-P)
