| >Description:
| 	dlopen(..., RTLD_NOW) returns non-null, even if the shared module
| 	it is asked to open contains unresolved symbols.
| 
| >How-To-Repeat:
| 	The following is the exact test case used by the configure script
| 	in pkgsrc/chat/ircservices:
| 
| 	% cat test-dlopen.c
| 	#include <dlfcn.h>
| 	int main(int argc, char **argv) {
| 		void *lib = dlopen("./test-lib.so", RTLD_NOW);
| 		printf("%d\n", lib != 0);
| 		if (lib)
| 			dlclose(lib);
| 		return 0;
| 	}
| 
| 	% cat test-lib.c
| 	int foo() {no_such_symbol();}
| 
| 	% cc -fPIC test-dlopen.c -o test-dlopen
| 	% cc -shared -fPIC test-lib.c -o test-lib.so
| 	% ./test-dlopen
| 	1
| 
| 	I expected the "test-dlopen" program to print "0", as it did on
| 	the NetBSD-1.6.2/i386 system I also tested this on.

Does this fix your problem?
