I've heard from others who had this problem. I can't figure it out and I've
never seen it myself. In my version of dln.c, it says:

#ifdef USE_DLN_DLOPEN
# ifdef __NetBSD__
#  include <nlist.h>
#  include <link.h>
# else
#  include <dlfcn.h>
# endif
#endif

So the question is, how did USE_DLN_DLOPEN get defined in your build?
Anyway, jus comment it out. Others here have reported no problems doing
that.
