Hi, While building 1.2.0 on Mac OS X 10.3.3 (Panther) I had a link error. The underlying CLN is version 1.1.6 built with gmp 4.1.2. The compiler is ranger> gcc --version gcc (GCC) 3.3 20030304 (Apple Computer, Inc. build 1495) Copyright (C) 2002 Free Software Foundation, Inc.

The multiply defined symbols are harmless, but the undefined symbols are the problem. Is this perhaps some link-ordering issue? Does anyone have any ideas?
