This change has nothing to do with *Net*BSD or indeed the problem I'm not 
describing very well.

So, here goes again...

In ltdl.c the following code exists

--- cut here ---
#if HAVE_LIBDL && !defined(__CYGWIN__)
      errors += lt_dlloader_add (lt_dlloader_next (0), &sys_dl, "dlopen");
#endif
#if HAVE_SHL_LOAD
      errors += lt_dlloader_add (lt_dlloader_next (0), &sys_shl, "dlopen");
#endif
#ifdef __WINDOWS__
      errors += lt_dlloader_add (lt_dlloader_next (0), &sys_wll, "dlopen");
#endif
#ifdef __BEOS__
      errors += lt_dlloader_add (lt_dlloader_next (0), &sys_bedl, "dlopen");
#endif
#if HAVE_DLD
      errors += lt_dlloader_add (lt_dlloader_next (0), &sys_dld, "dld");
#endif
      errors += lt_dlloader_add (lt_dlloader_next (0), &presym, "dlpreload");

-- cut here ---

For NetBSD non of HAVE_LIBDL, HAVE_SHL_LOAD, HAVE_DLD are true and so 
"dlopen" doesn't get added as a loader.

dlopen does exist. It just exists in libc and not libdl.
