I think I have found a more simple solution: in configure
(acinclude.m4) do the check for MacOS X first and only if it wasn't
found, check for libdl/dlopen/dlfcn.h.

An updated configure script is at
http://www.meier-geinitz.de/sane/tmp/configure and in CVS.

There is also a complete unofficial snapshot at
http://www.meier-geinitz.de/sane/snapshots/

Please, MacOS X users, test if it works with and without libdl.

Bye,
  Henning
