ghcilink003 and ghcilink006 fail on OSX

ghcilink003 and ghcilink006 fail on OSX (both x86 and amd64) for me, e.g.

=====> ghcilink003(normal) 3 of 6 [0, 0, 0]
cd . && $MAKE -s --no-print-directory ghcilink003    </dev/null >ghcilink003.run.stdout 2>ghcilink003.run.stderr
Wrong exit code (expected 0 , actual 2 )
Stdout:

Stderr:
<command line>: user specified .o/.so/.DLL could not be loaded (dlopen(/usr/lib/gcc/i686-apple-darwin10/4.2.1/libstdc++.dylib, 9): no suitable image found.  Did find:

make[1]: *** [ghcilink003] Error 1

This seems to be because I can't dlopen libstdc++.dylib:

$ cat q.c

#include <dlfcn.h>
#include <stdio.h>

int main(void) {
    void *p;
    p = dlopen("/usr/lib/gcc/i686-apple-darwin10/4.2.1/libstdc++.dylib", RTLD_LAZY);
    printf("Result: %p\n", p);
    printf("Error: %s\n", dlerror());
    return 0;
}

$ gcc q.c -o q
$ ./q 
Result: 0x0
