Subject: Initializing $LOAD_PATH manually? (embedding ruby)

Hi,

I am embedding ruby in an application and shipping it with app as  
well, so I need to setup the load path manually instead of calling  
ruby_init_loadpath(). Here is the code:

	NSBundle *bundle = [NSBundle mainBundle];
	NSString *path = [NSString stringWithFormat:@"%@/../Resources/ruby",  
[bundle pathForAuxiliaryExecutable:@"My App"]];
	load_path = rb_ary_new();
	rb_ary_push(load_path, rb_str_new2([[NSString stringWithFormat:@"%@/% 
s", path, "site_ruby/1.8"] UTF8String]));
	rb_ary_push(load_path, rb_str_new2([[NSString stringWithFormat:@"%@/% 
s", path, "site_ruby/1.8/powerpc-darwin8.7.0"] UTF8String]));
	rb_ary_push(load_path, rb_str_new2([[NSString stringWithFormat:@"%@/% 
s", path, "site_ruby"] UTF8String]));
	rb_ary_push(load_path, rb_str_new2([[NSString stringWithFormat:@"%@/% 
s", path, "1.8"] UTF8String]));
	rb_ary_push(load_path, rb_str_new2([[NSString stringWithFormat:@"%@/% 
s", path, "1.8/powerpc-darwin8.7.0"] UTF8String]));
	rb_gv_set("$:", load_path);

I get this error:

	ruby: $: is a read-only variable (NameError)

How can I get around this?

Thanks,
