[Ecls-list] How can I build 64-bit OS X ?

[Dr. David Kirkby]

I'm trying to build ecl (as part of Sage) on

$ uname -a
Darwin bsd.local 9.8.0 Darwin Kernel Version 9.8.0: Wed Jul 15 16:55:01 
PDT 2009; root:xnu-1228.15.4~1/RELEASE_I386 i386 i386 MacPro1,1 Darwin


The compiler is gcc. These variables were set:


Using CC=gcc
Using CXX=g++
Using CFLAGS= -O2  -m64  -g  -Wall
Using CXXFLAGS= -O2  -m64  -g  -Wall
Using CPPFLAGS= -I/Users/kirkby/64/sage-4.1.2.alpha0/local/include
Using LDFLAGS= -L/Users/kirkby/64/sage-4.1.2.alpha0/local/lib

then it was configured with:

./configure --prefix=$SAGE_LOCAL --with-system-gmp --enable-boehm=system

but it fails as below:

Any ideas?
