It is a platform bug, RTLD_LOCAL doesn't work on 10.3. The following  
C snippet fails with the same error as ctypes: FAIL: dlcompat: unable  
to open this file with RTLD_LOCAL. This seems to be confirmed by this  
sourcet test file from darwin: http://darwinsource.opendarwin.org/ 
10.4.1/dyld-43/unit-tests/test-cases/dlopen-RTLD_LOCAL/main.c.

/* Begin of file */
#include <dlfcn.h>
#include <stdio.h>

int main(void)
{
         void* lib;

         lib = dlopen("/usr/lib/libz.dylib", RTLD_LOCAL);
         if (lib == NULL) {
                 printf("FAIL: %s\n", dlerror());
         } else {
                 printf("OK\n");
         }
         return 0;
}
/* End of file */
